[0001] The present invention relates to the technical field of microwave power measurement, and in particular to a microwave power measurement and verification method, a storage medium, and a controller. Background Art

[0002] Megawatt (MW)-class gyrotrons are used for auxiliary heating of fusion plasmas and are currently recognized as the only microwave source suitable for electron cyclotron resonance heating (ECRH), current drive (CD), and electron Bernstein wave heating systems in magnetic confinement fusion devices. Within a gyrotron, the diamond window and oil tank are two key functional components, responsible for microwave output and thermal management, respectively.

[0003] The main methods for measuring the power of MW-class gyrotron components include liquid calorimetry and directional coupler detection. Liquid calorimetry converts microwave energy into the thermal energy of a liquid (primarily water) and then uses heat measurement to measure microwave power. Due to its maturity and flexibility, it is widely used. However, if the calorimetric method fails due to temperature transmitter failure, environmental vibration, or interference from external heat sources, the measured power may not truly reflect the operating status of the diamond window and oil cartridge, posing a safety hazard to the gyrotron's operation. Therefore, to ensure the safe operation of the gyrotron, a reliable calibration method for measuring the power of key gyrotron components (diamond window and oil cartridge) is crucial.

[0021] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0022] It should be noted that when conducting long pulse high power experiments on MW-level gyrotrons, the diamond window needs to continuously withstand the transmission loss of high power microwaves (such as 1MW), and the loss tangent is generally required to be Excessive losses can cause a large local temperature rise in the diamond window, reducing microwave transmission efficiency and even causing microcracks due to uneven thermal expansion. Therefore, the power of the diamond window must be measured in real time, and the experiment must be stopped if the power exceeds the limit. In addition, real-time monitoring of the oil box power plays an important role in ensuring the safe operation of the gyrotron. Abnormal power increases can indicate abnormal cathode operating conditions. When the electron beam velocity distribution deviates from the design parameters, the energy conversion efficiency will be significantly reduced. At the same time, this monitoring can also effectively prevent the failure of the oil cooling system. If the oil temperature exceeds the boiling point of the medium and causes vaporization, it will cause insulation performance degradation and induce local arc discharge accidents.

[0023] Currently, there are no projects with comprehensive theoretical support and practical application for power measurement and calibration methods for key gyrotron components (diamond windows and oil cartridges). Most research focuses on designing power measurement and calibration schemes at the gyrotron's absorption load or microwave output unit (MOU), using calorimetry to verify the accuracy of power detection.

[0024] The relevant gyrotron microwave power measurement system and calibration method have limitations in engineering applications. For example, the large size of the calibration equipment limits its spatial adaptability to the microwave test bench, insufficient turbulent mixing restricts the accuracy of temperature field characterization, and there is a lack of verification of the calibration coefficient k (which theoretically represents the product of the specific heat capacity C of cooling water and the flow rate F), which affects the accuracy of the microwave power measurement results.

[0025] To solve the above problems, the present invention provides a microwave power measurement and calibration method, storage medium, and controller. The microwave power measurement and calibration method, storage medium, and controller of the present invention are described in detail below with reference to the accompanying drawings and specific implementations.

[0026] The microwave power measurement and verification method of the embodiment of the present invention is used in a water-cooling circulation system for measuring the power of multiple components of a megawatt-level gyrotron, wherein the water-cooling circulation branch of each component is connected in series with an electric heating module.

[0027] In one embodiment of the present invention, the component includes at least one of a diamond window and an oil box.

[0028] Specifically, several components within the megawatt-class gyrotron are key, such as the diamond window and oil cartridge. The water-cooling system includes a corresponding water-cooling circuit branch for each component. Each corresponding water-cooling circuit branch is connected in series with an electric heating module with precisely calibrated power parameters. This module heats the cooling water within the corresponding water-cooling circuit branch.

[0029] The water cooling circulation system in the embodiment of the present invention is provided with a water cooling pipeline, a valve, a pressure transmitter, a flow transmitter, a temperature transmitter, etc.

[0030] In a specific embodiment of the present invention, when the water cooling circulation system is used for multiple components of a megawatt-class gyrotron, the water cooling circulation system is as follows: Figure 1 As shown, the water cooling circuit consists of a water supply pipe, a return pipe, and a flexible connecting hose. Cooling water flows through the water supply main along a predetermined path for primary diversion, then through the water supply branch pipe for terminal diversion. Finally, it is directed through a flexible hose to the electric heating module. After heat exchange, the cooling medium is injected into the equipment end (diamond window, oil box) through the outlet of the electric heating module. After heat load transfer, it is discharged from the equipment end outlet, converges along the return branch pipe, and finally returns to the circulating cooling system through the return main pipe, forming a closed-loop cooling circuit.

[0031] This piping architecture achieves stable transmission and heat exchange control of the cooling medium under complex working conditions through the diversion / convergence topology design and the stress compensation function of the flexible connection components.

[0032] In this specific embodiment, the valve system consists of a ball valve assembly, a stop valve, and a drain valve. The ball valve assembly is located at the beginning of the water supply branch along the medium flow direction, the end of the return branch along the medium flow direction, and the media access front end of the pressure transmitter assembly, configured to control the on / off switching of the cooling water. The stop valve is integrated into the water supply branch, downstream of the ball valve assembly, and is configured to regulate the flow and pressure parameters of the medium entering the equipment end (diamond window, oil box). Drain valves are located at the end node of the water supply branch and the beginning node of the return branch, configured to drain the pipeline in specific sections.

[0033] The valve body layout realizes the integration of multiple functions of cooling medium flow control, pressure regulation and system emptying through spatial topology optimization.

[0034] In this specific embodiment, the pressure transmitter includes a water supply pressure transmitter installed on the water supply branch and a return water pressure transmitter installed on the return water branch, which dynamically monitor the water supply pressure parameters and the return water pressure parameters in the circulating water circuit.

[0035] Practically, the pressure transmitter assembly has a built-in physical quantity sensing module and a signal conversion module, which performs analog-to-digital conversion processing on the pressure physical quantity through the piezoresistive effect, generates a standardized electrical signal, and transmits it to the control system.

[0036] In this specific embodiment, the flow transmitter is installed on the water supply branch and adopts a turbine flow meter with a built-in turbine rotor assembly and a photoelectric encoder. It is configured to achieve high-precision dynamic measurement of the fluid flow in the circulating water circuit through a linear coupling relationship between the turbine speed and the flow velocity of the water medium, and transmit it to the control system through electrical signals.

[0037] In this specific embodiment, the temperature sensing system includes a supply water temperature transmitter and a return water temperature transmitter. The supply water temperature transmitter is installed at the fluid transmission node of the supply water branch, while the return water temperature transmitter is installed at the heat exchange monitoring station of the return water branch. These transmitters are configured to accurately and dynamically monitor the temperature parameters of the supply and return water media in the circulating water circuit.

[0038] Practically, the temperature transmitter component has a built-in PT100-type platinum-based thin film resistor sensor element, which converts the temperature physical quantity into a resistance change through a wide temperature range linear response characteristic. After being converted into a voltage signal through a Wheatstone bridge, it generates an electrical signal through a signal conditioning circuit and is finally transmitted to the control system.

[0039] It should be noted that the embodiment of the present invention does not limit the specific structure of the water cooling circulation system, and water cooling circulation systems with other structures may also be used.

[0040] The electric heating module in the embodiment of the present invention utilizes a micro-electric heater with precisely calibrated power parameters. Exemplarily, the micro-electric heater has a compact structure with an axial extension of 220 mm (millimeter) and a radial span of 70 mm. The micro-electric heater integrates a nickel-chromium alloy (Ni-Cr) resistance wire as the core heat source component and utilizes a metal tube-wrapped resistance heating mode with a nominal power of 4 kW. The water inlet port of the micro-electric heater is fluidically coupled to the water supply branch via a flexible hose assembly, while the water outlet port establishes a heat conduction link with the device terminal (diamond window, oil box) via the flexible hose assembly. The device is configured to apply steady-state heat loading to the cooling medium on the water supply side and deliver it in a targeted manner to the device terminal.

[0041] Figure 2 FIG. 1 is a flow chart of a microwave power measurement and calibration method according to an embodiment of the present invention. Figure 2 As shown, the microwave power measurement calibration method may include: S101, while controlling the electric heating modules in the water-cooling circulation branches corresponding to each component to heat, obtain the flow rate, supply side temperature, and return side temperature of the cooling water in the water-cooling circulation branches corresponding to each component, and calculate the real-time thermal power value of the water-cooling circulation branches corresponding to each component; S102, determining, based on the real-time thermal power value of the water cooling circulation branch corresponding to each component, that the water cooling circulation branch corresponding to each component has reached a thermodynamic steady state, and recording the real-time thermal power value of the water cooling circulation branch corresponding to each component after reaching the thermodynamic steady state as the power plateau value of each component; S103, using the standard electric power value of the electric heating module to calibrate the power flat-top value of each component, and after passing the calibration, cross-validate the power flat-top value of each component to verify the accuracy of the water cooling circulation system measurement.

[0042] The present invention connects an electric heating module in series with the water-cooling circulation branch corresponding to the key components of a megawatt-class gyrotron. This module simulates the heating effect of a microwave source on the water-cooling pipe and enables power measurement and verification of the key components of the megawatt-class gyrotron based on the principle of calorimetry.

[0043] Specifically, the electric heating modules in the water-cooling circulation branches corresponding to each component are controlled to activate and operate in a controllable heating mode to heat the cooling water in the water-cooling circulation system's supply branch. The heated medium (cooling water) is then injected into the return branch after completing heat transfer at the component equipment end. During this process, the flow rate, as measured by the flow transmitter, the inlet water temperature, as measured by the supply water temperature transmitter, and the return water temperature, as measured by the return water temperature transmitter, are collected in real time on each component's corresponding water-cooling circulation branch. Using the relevant heat-to-work conversion equation, the real-time thermal power value of each component's corresponding water-cooling circulation branch is calculated based on the cooling water flow rate, supply water temperature, and return water temperature in the cooling water circulation branch.

[0044] Determine whether each component's corresponding water-cooling circulation branch has reached thermodynamic steady state based on the component's corresponding water-cooling circulation branch's real-time thermal power value. After determining that a component's corresponding water-cooling circulation branch has reached thermodynamic steady state, obtain the component's corresponding water-cooling circulation branch's real-time thermal power value after reaching thermodynamic steady state. This real-time thermal power value after reaching thermodynamic steady state is recorded as the component's power plateau value, until the power plateau value for each component is determined.

[0045] The power plateau values of each component were calibrated using the standard electrical power value of the electric heating module, and cross-validated. If the relative error between the component power plateau value and the standard electrical power value is within a reasonable range, and there is no significant difference in the power plateau values between the components, it can be verified that the power measurement system for the key components of the gyrotron (diamond window, oil cartridge) has high measurement accuracy and can effectively represent the true power absorbed by the key components of the microwave system.

[0046] It should be noted that if there is a power plateau value of a component that has not passed the calibration and / or verification, the water-cooling circulation branch corresponding to the component should be troubleshooted, and after the troubleshooting and repair, the microwave power measurement and calibration method in the embodiment of the present invention should continue to be used for power measurement and calibration.

[0047] The embodiment of the present invention provides a reliable measurement guarantee for power monitoring of key components of the gyrotron by establishing a traceable power benchmark (the standard electric power value of the electric heating module).

[0048] It should be noted that embodiments of the present invention can utilize a single electric heating module, i.e., sequentially connect the electric heating module to the water-cooling circulation branch corresponding to each component, to achieve power measurement and verification of key gyrotron components. Alternatively, multiple electric heating modules can be utilized, i.e., each electric heating module is connected to the water-cooling circulation branch corresponding to multiple components, to achieve power measurement and verification of key gyrotron components. Embodiments of the present invention do not limit the specific implementation method of connecting the electric heating module to the water-cooling circulation branch.

[0049] The microwave power measurement and verification method of the present invention integrates a micro-electric heating module with precisely calibrated power parameters in series with the water-cooling circulation branch of a key gyrotron component. The micro-electric heating module is controlled by a controllable heating mode to heat the cooling water. After the water-cooling circulation branch reaches thermodynamic steady state, the cooling water flow rate and the supply and return temperatures are measured. The thermal power value of each component in the water-cooling circulation branch is calculated using the relevant heat-to-work conversion equations. This thermal power value is recorded as the power plateau value of each component. The power plateau value of each component is then calibrated using the standard electric power value of the electric heating module, and after passing the calibration, the power plateau value of each component is cross-validated. Passing both calibration and verification indicates that the power measurement system for key gyrotron components (diamond window, oil cartridge) has high measurement accuracy and can effectively characterize the actual power absorbed by key components in a microwave system.

[0050] In one embodiment of the present invention, Figure 3 As shown, before controlling each component to heat the electric heating module in the corresponding water cooling circulation branch, the microwave power measurement and verification method may further include: S201, start the water cooling circulation system and stabilize the cooling water of the water cooling circulation system at a target temperature.

[0051] Specifically, the water-cooling system was started and the cooling water temperature was stabilized at (11±0.5)°C (the target temperature). During startup, the valve configuration operations were performed sequentially: first, the ball valve at the end of the return branch was opened to unlock the return channel, then the ball valve at the beginning of the supply branch was opened to establish the water supply path. Finally, the ball valve at the front of the pressure transmitter was activated to complete the sensor link.

[0052] S202, regulating the water supply pressure and flow of each water cooling circulation branch, controlling the water supply pressure corresponding to each water cooling circulation branch within a target pressure range, and stabilizing the flow of each water cooling circulation branch at a target flow.

[0053] Specifically, the shut-off valves in each water-cooling circulation branch are adjusted to control the water supply pressure of the water channel corresponding to each component within the target pressure range, while stabilizing the flow rate of the water channel corresponding to each component at the target flow rate.

[0054] It should be noted that the target pressure range and target flow rate for different components are different. Among them, the target pressure range of the diamond window corresponding to the water channel is below 3.5 bar. The target pressure range of the oil box corresponding to the water channel is below 3 bar. The target flow rate of the diamond window corresponding to the water channel is 0.45 The target flow rate of the oil box corresponding to the water channel is 0.4 .

[0055] In a specific embodiment of the present invention, Figure 4 As shown, calculating the real-time thermal power value of the water cooling circulation branch corresponding to each component may include: S301, calculating the supply / return side temperature difference of the water cooling circulation branch corresponding to each component based on the supply side temperature and return side temperature of the water cooling circulation branch corresponding to each component; S302 , using a heat power conversion equation, calculate the real-time heat power value of the water cooling circulation branch corresponding to each component based on the flow rate and the supply / return water side temperature difference of the water cooling circulation branch corresponding to each component.

[0056] Specifically, the supply / return side temperature difference of the water cooling circulation branch corresponding to each component is calculated based on the supply side temperature and return side temperature of the water cooling circulation branch corresponding to each component. The heat power conversion equation is used: , calculate the real-time thermal power value of the target water cooling circulation system according to the flow rate of the water cooling circulation branch corresponding to each component and the temperature difference between the supply and return water sides. Indicates the thermal power value, is the specific heat capacity of water (unit: J / (kg·℃)), is the density of water (unit: kg / m3), For traffic, is the temperature difference between the supply and return water sides.

[0057] The above-mentioned specific heat power conversion equation of the embodiment of the present invention is constructed as follows: During the heating process of the electric heating module, During this time, the increment of thermodynamic energy generated by the cooling medium flowing through the tested component is: (1) in, is the specific heat capacity of water (unit: J / (kg·℃)), for The mass of cooling water flowing out during the time (unit: kg); is the temperature of the return pipe (unit: °C), is the initial moment, It is the time for cooling water to flow from the water supply end to the return end of the tested component. Temperature of the water supply pipe (unit: °C).

[0058] During the calibration process, the water temperature of the water supply pipe remains unchanged. .

[0059] Let the temperature change , then: (2) Let the cooling water flow be (unit: ),but , is the density of water (unit: ), then: (3) according to , for The average thermal power of water in time, combined with formula (3), we have: .

[0060] In a specific embodiment of the present invention, Figure 5 As shown, determining whether the water cooling circulation branch corresponding to each component reaches a thermodynamic steady state based on the real-time thermal power value of the water cooling circulation branch corresponding to each component may include: S401, calculating the change rate of the real-time thermal power value of the water cooling circulation branch corresponding to each component to obtain the thermal power change rate of the water cooling circulation branch corresponding to each component; S402: When the thermal power change rate of the water-cooling circulation branch corresponding to the component is less than a preset change range, it is determined that the water-cooling circulation branch corresponding to the component has reached a thermodynamic steady state.

[0061] Specifically, the real-time thermal power value changes of the water-cooling circulation branches corresponding to each component are monitored in real time to determine whether the water-cooling circulation branches corresponding to each component have reached a thermodynamic steady state.

[0062] It is feasible to calculate the rate of change of the real-time thermal power value of the water-cooling circulation branch corresponding to the component. When the rate of change is less than the preset change range, it means that the real-time thermal power value of the water-cooling circulation branch corresponding to the component is stable or fluctuates within a small range, that is, it reaches a plateau value. At this time, it can be determined that the water-cooling circulation branch corresponding to the component has reached thermodynamic steady state.

[0063] In one embodiment of the present invention, the microwave power measurement and calibration method further includes: When it is determined that the water-cooling circulation branch corresponding to the component has reached a thermodynamic steady state, the electric heating device in the water-cooling circulation branch corresponding to the component is controlled to continue heating for a preset time and then stop heating.

[0064] Specifically, when it is determined that the water-cooling circulation branch corresponding to the component has reached a thermodynamic steady state, the electric heating module in the water-cooling circulation branch corresponding to the component is controlled to continue heating for a preset time and then stop heating, such as continuing heating for 5 minutes and then stopping heating. It should be noted that the embodiment of the present invention does not limit the preset time, and the preset time can also be 3 minutes, 4 minutes, 6 minutes, etc. When it is determined that the water-cooling circulation branch corresponding to the component has reached a thermodynamic steady state, the electric heating module in the water-cooling circulation branch corresponding to the component is controlled to continue heating for a preset time, so that more stable real-time thermal power values, that is, power plateau values, can be obtained.

[0065] In a specific embodiment of the present invention, the power plateau value of each component is checked using the standard electric power value of the electric heating module, which may include: Calculate the ratio of the difference between the power flat-top value of each component and the standard electric power value to the standard electric power value, and take the absolute value to obtain the absolute value of the first ratio corresponding to each component; Determine whether the absolute value of the first ratio corresponding to each component is less than or equal to a first preset threshold; If yes, it is determined that the verification has been passed; If not, it is determined that the calibration has failed.

[0066] Specifically, the power peak value of each component is compared with the standard electric power value of the electric heating device. , calculate the differences Standard electric power value Ratio , and take the absolute value , determine the absolute value of the first ratio corresponding to each component Are they all less than or equal to the first preset threshold. If the absolute value of the first ratio corresponding to each component If the absolute value of the first ratio corresponding to any component is less than or equal to the first preset threshold, it is determined that the calibration has been passed, and it can be determined that the power measurement system of each component has passed the first level calibration. If the value is greater than the first preset threshold, it is determined that the calibration has not been passed, and the water cooling circulation branch of the component that has not passed the calibration can be troubleshooted.

[0067] In a specific example of the present invention, the first preset threshold may be 5%. It should be noted that the embodiment of the present invention does not limit the first preset threshold.

[0068] In a specific embodiment of the present invention, cross-validation of the power peak value of each component may include: Calculating the ratio of the difference between the power peak values of each component to the power average value, and taking the absolute value to obtain a plurality of second ratio absolute values, wherein the power average value is the power average of the power peak values of each component; Determining whether the absolute values of the second ratios are all less than or equal to a second preset threshold; If so, the verification is confirmed to be successful; If not, it is determined that the verification has not passed.

[0069] Specifically, calculate the difference between the power peak values of each component and the power average value ratio.

[0070] For example, when two components are measured, and the two components are a diamond window and an oil box, the diamond window power flat top value is calculated. Oil box power flat top value The average value of power is obtained Calculate the diamond window power flat top value Flat top value with oil box power The difference Calculate the difference and the average power Ratio And take the absolute value , determine the absolute value of the second ratio Is it less than or equal to the second preset threshold? If the absolute value of the second ratio is less than or equal to the second preset threshold, verification is determined to have passed, and the diamond window and oil cartridge power measurement system can be determined to have passed the second-level calibration, indicating that the water-cooling circulation system is measuring accurately. If the absolute value of the second ratio is greater than the second preset threshold, verification is determined to have failed, and the diamond window and oil cartridge power measurement system has failed the second-level calibration, indicating that the water-cooling circulation system is measuring inaccurately, and troubleshooting of the water-cooling circulation branch of the corresponding component is required.

[0071] In a specific example of the present invention, the second preset threshold may be 3%. It should be noted that the embodiment of the present invention does not limit the second preset threshold.

[0072] It should be noted that when taking the power flat-top values of each component for the above-mentioned verification and cross-validation, any one or more of the power flat-top values corresponding to the component can be taken for the above-mentioned verification and cross-validation, or the average value of multiple power flat-top values of the component can be taken and the average value can be recorded as the power flat-top value of the component for the above-mentioned verification and cross-validation.

[0073] The microwave power measurement and calibration method in the embodiment of the present invention can be used for a water-cooling circulation system having multiple MW-level gyrotron test platforms.

[0074] As a specific embodiment, Figure 6 As shown, in the water-cooling circulation system used for two MW-class gyrotron test platforms (1# and 2#), cooling water flows along a predetermined flow path, sequentially through water supply main 1 for primary diversion, through primary water supply branch 2 for secondary diversion, and then through secondary water supply branch 3 for terminal diversion. Finally, it is directed through flexible hose 10 to electric heating module 11. After heat exchange, the cooling medium is injected from the outlet of electric heating module 11 into the equipment end (1# diamond window 12, 1# oil box 16, 2# diamond window 18, 2# oil box 19). After completing the heat load transfer, it is discharged from the equipment end outlet, flows along secondary return branch 13 for primary confluence, and then through primary return branch 17 for secondary confluence. Finally, it returns to the circulating cooling system through return main 20, forming a closed-loop cooling loop. The piping architecture of this water-cooling circulation system achieves stable transmission and heat exchange control of the cooling medium under complex working conditions through a multi-stage diversion / convergence topology design and stress compensation function of flexible connection components.

[0075] In this specific embodiment, ball valves 4 are located at the beginning of the secondary water supply branch along the medium flow direction, at the end of the secondary return branch along the medium flow direction, and at the media access front end of the pressure transmitter assembly, configured to perform cooling water on / off control. A stop valve 5 is integrated into the downstream position of the ball valve group in the secondary water supply branch and is configured to regulate the flow and pressure parameters of the medium entering the equipment. Drain valves 9 are located at the end node of the secondary water supply branch and the front node of the secondary return branch and are configured to implement pipeline emptying functions for specific pipe sections. This valve body layout achieves the multi-functional integration of cooling medium flow control, pressure regulation, and system emptying through spatial topology optimization.

[0076] In this specific embodiment, the pressure transmitter includes a water supply pressure transmitter 6 installed on the secondary water supply branch and a return water pressure transmitter 15 installed on the secondary return water branch, which perform dynamic monitoring of the water supply pressure parameters and return water pressure parameters in the circulating water circuit. The water supply flow transmitter 7 is installed on the secondary water supply branch and is configured to achieve high-precision dynamic measurement of the fluid flow in the circulating water circuit through the linear coupling relationship between the turbine speed and the flow velocity of the water circuit medium. The water supply temperature transmitter 8 is installed at the fluid transmission node of the secondary water supply branch and is configured to perform precise dynamic monitoring of the temperature parameters of the water supply medium in the circulating water circuit. The return water temperature transmitter 14 is installed at the heat exchange monitoring station of the secondary return water branch and is configured to perform precise dynamic monitoring of the temperature parameters of the return water medium in the circulating water circuit.

[0077] In this specific embodiment, the water inlet port of the electric heating module 11 forms a fluid coupling with the secondary water supply branch through a flexible hose assembly, and the water outlet port establishes a heat conduction link with the equipment terminal through the flexible hose assembly, and is configured to implement steady-state heat loading on the cooling medium on the water supply side and transport it to the equipment terminal in a direction.

[0078] When measuring and calibrating the power of the diamond windows and oil cartridges of the two MW-class gyrotrons described above using the microwave power measurement and calibration method of the embodiment of the present invention, the water cooling circulation systems of the two MW-class gyrotron test platforms are activated to stabilize the water temperature at (11±0.5)°C. Practically, the valve configuration operations are performed sequentially: a) opening the end ball valve of the secondary return branch to unlock the return channel; b) opening the beginning ball valve of the secondary supply branch to establish a water supply path; c) activating the front ball valve of the pressure transmitter to complete the sensor link connection. Adjusting the shutoff valves of each water channel controls the water supply pressure of the water channel corresponding to the diamond window and the oil cartridge to below 3.5 bar and 3 bar, respectively. Simultaneously, the flow rates of the water channels corresponding to the diamond window and the oil cartridge are adjusted to 0.45 m³ / h and 0.4 m³ / h, respectively, and remain stable. Turn on the electric heating modules on the four branches of the two test platforms, and implement heat loading on the medium of the secondary water supply branch. The heated medium is injected into the secondary water return branch after completing heat conduction through the equipment end (diamond window, oil box). During this process, the flow transmitter, water supply temperature transmitter and return water temperature transmitter respectively monitor the flow, inlet water temperature and return water temperature of the branch in real time, and transmit the signal to the control system through the cable. In the control system, the real-time power of each key component (diamond window, oil box) is calculated through the set power calculation formula. In order to observe the power changes of the diamond window and oil box in the control system, when the power is stable or fluctuates within a small range, that is, after reaching the flat top value, continue heating for more than five minutes, and then stop heating. The standard electric power value of the electric heating module is set to (4kW) and compare the data with the power peak value of key components. If the Engineering tolerance range ( The component power flat-top value and the standard electric power value The power measurement system of the component passes the first level calibration. Further cross validation is performed: the relative deviation of the power flat top value of the diamond window and the oil box is compared. If the relative deviation of the power flat top value of the diamond window and the oil box is satisfied, ( is the diamond window power flat-top value, is the oil box power flat top value, is the average of the diamond window and oil box power flat-top values), the system is judged to have passed the secondary calibration, and the full-dimensional metrological verification of the measurement system is completed.

[0079] The embodiments of the present invention implement microwave power measurement calibration based on the principle of thermodynamic substitution during calibration. An electric heating module replaces the microwave source as the standard power input device, applying equivalent heat loading to the water-cooled circulation system of the key components of the gyrotron. Under steady-state heat exchange conditions, the cooling medium, heated by the electric heating module, flows through the measured components (diamond window, oil box), causing a sustained and stable temperature rise in the return water pipeline. Based on the law of conservation of energy in heat transfer, the actual thermal power value is calculated by quantifying the temperature rise parameters of the cooling medium and the fluid dynamics parameters. This is then compared and analyzed with the calibrated power (standard electrical power value) of the electric heating module, thereby verifying the metrological accuracy of the power measurement system.

[0080] During the calibration process, it is assumed that the output energy of the electric heating module is converted into the heat energy of water. Within a certain time, the system reaches a thermodynamic steady state, the temperature of the return pipe remains constant, and when it reaches the plateau value, is a constant value T0, then the average thermal power of water is Is a constant, approximately equal to the standard electric power value of the electric heating module (4kW).

[0081] The embodiments of the present invention have been put into practical application. In a verification experiment on the power measurement system of the key components (diamond window and oil box) of the MW-class gyrotron in the CRAFT-ECRH (China Research Facility for Advanced Fusion Technology, a comprehensive research facility for key systems of fusion reactor hosts) test platform, the power measurement system of the diamond window and oil box was calibrated by using the method of the embodiment of the present invention, confirming that its performance indicators met the design requirements. Figures 7(a), 7(b), 8(a), 8(b) and Figure 9 Statistical data curves for calibrating the power measurement system (Figures 7(a), 7(b), 8(a), 8(b) and Figure 9 The horizontal axis is time, and the vertical axis is temperature / °C. Fig. 7(a) shows the temperature variation curve of the 1# diamond window, Fig. 7(b) shows the temperature variation curve of the 1# oil box, Fig. 8(a) shows the temperature variation curve of the 2# diamond window, and Fig. 8(b) shows the temperature variation curve of the 2# oil box. Figure 9 The following are the power variation curves of the diamond window and oil box of two MW-class gyrotron test benches. Figure 9 The left curve in the first row is the power change curve of 1# diamond window, the right curve in the first row is the power change curve of 1# oil box, the left curve in the second row is the power change curve of 2# diamond window, and the right curve in the second row is the power change curve of 2# oil box.

[0082] According to the data corresponding to the above curves, a table is drawn to obtain the following Table 1.

[0083] Table 1 Calibration data of power measurement system for key components of two MW-class gyrotrons

[0084] Note: The power calibration experiment is carried out under standard atmospheric pressure, the specific heat capacity C of water is taken as 4.2 kJ / (kg·℃), and the density ρ is taken as 1000 kg / m3.

[0085] As can be seen from Table 1, the power flat-top value of each key component power measurement Standard electric power value of electric heating module (4kW) data comparison, all meet The engineering tolerance range, while the power between the components Also approximately equal, satisfying , it is determined that the measurement system has passed the double calibration and completed the metrological verification.

[0086] In response to the shortcomings of existing technologies, the present invention proposes a method for power measurement and calibration of key components (diamond windows and oil cartridges) of MW-class gyrotrons. By connecting an external micro-electric heating module to simulate the heating effect of a microwave source on the water-cooling pipe, dual calibration of the power measurement system is achieved based on the principles of calorimetry. Compared to traditional solutions, this method utilizes a micro-electric heating module, which is easy to install and disassemble, effectively resolving the issue of poor spatial adaptability of large-scale calibration equipment. Furthermore, by connecting the module in series to the water-cooling pipe, water flow disturbances are minimized, ensuring the reliability of water temperature measurement data. Furthermore, by optimizing the calibration process, operation time is shortened, reducing the impact of environmental variables such as air temperature and pressure on calibration accuracy.

[0087] The embodiment of the present invention configures high-precision flow transmitters and temperature transmitters in the water channel, which can accurately monitor the dynamic flow and temperature parameters of cooling water in real time, and transmit the data to the control system for power calculation and curve drawing, intuitively presenting the power change trends of various components of the gyrotron, solving the problem that traditional power measurement requires repeated calibration of the coefficient k and lacks a verification mechanism, and realizes the self-verification function of the measurement system.

[0088] The embodiment of the present invention constructs a dual calibration system, which can not only compare and calibrate the power of the electric heating module with the power detected by the key component power detection system, but also cross-compare and calibrate the power of each component. This composite calibration mechanism greatly improves the reliability of the calibration results and provides dual guarantees for the accurate measurement of microwave power and safe operation of MW-level gyrotrons.

[0089] The microwave power measurement and calibration method of an embodiment of the present invention utilizes an external micro-electric heating module to simulate the heating effect of a microwave source on a water-cooling pipeline, and implements dual calibration of the power measurement system based on the principle of calorimetry. The micro-electric heating module is small in size and easy to install and disassemble. Its serial connection to the water-cooling pipeline causes minimal disturbance to the water flow, making it highly compatible with MW-class gyrotron test benches. The calibration process is quick and avoids the effects of environmental variables such as temperature and pressure on calibration accuracy. The calibration factor k (the product of the specific heat capacity C of water and the pipeline cooling water flow F) is not required, which simplifies the calibration steps and reduces power measurement errors. A traceable verification system for thermal parameter measurement of MW-class high-power microwave devices has been established. It can be applied to the calibration of power detection systems of other microwave devices, except for diamond windows and oil boxes.
