[0038] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0039] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0040] In practical applications, the high-voltage control system is a crucial component of tandem accelerators, and its stability and accuracy directly impact the acceleration effect. Current high-voltage control systems used in tandem accelerators exhibit slow and coarse adjustment of the corona current at the corona needle tip, resulting in insufficient flexibility and an inability to meet the diverse acceleration application requirements of tandem accelerators.

[0041] Based on the above problems, this application provides a voltage adjustment method, device, and high-voltage control system.

[0042] This application first provides a voltage adjustment method, which is applied to a high-voltage control system; the high-voltage control system includes a steel barrel with a beam channel.

[0043] In one embodiment, the aforementioned high-voltage control system can be applied to a tandem accelerator.

[0044] In one embodiment, the beam channel can be fixedly installed in the steel drum, or its installation method can be flexibly adjusted; for example, the above installation method may include parameters such as the installation position or the diameter of the beam channel.

[0045] In one embodiment, the shape, size, high-pressure end, and low-pressure end of the steel drum can be flexibly adjusted or configured.

[0046] Figure 1 This is a schematic flowchart of the voltage adjustment method provided in the embodiments of this application, as shown below. Figure 1 As shown, the method may include the following steps:

[0047] Step 101: Obtain at least an analog signal associated with the initial electrostatic field in the steel drum.

[0048] The analog signals include AC analog electrical signals and / or DC analog electrical signals; the initial electrostatic field is associated with the initial voltage applied to the steel drum.

[0049] In one implementation, the initial voltage may include the voltage configured to the steel drum at the current moment; for example, the amplitude of the initial voltage may be greater than or equal to a voltage threshold, or in other words, the amplitude of the initial voltage may be in a high voltage range.

[0050] In one implementation, the data type of the initial voltage can be either analog or digital.

[0051] In one embodiment, the initial electrostatic field may include the electrostatic field inside the steel drum caused by an initial voltage set between the high-voltage end and the low-voltage end inside the steel drum.

[0052] In one implementation, an AC analog electrical signal can be used to characterize the changing state of an initial electrostatic field; for example, the AC analog electrical signal may include analog AC voltage and / or AC current.

[0053] In one embodiment, a DC analog electrical signal can characterize the stable state of the initial electrostatic field at least for a specified time.

[0054] In one implementation, the analog signal can be obtained in any of the following ways:

[0055] An analog signal acquisition device installed inside the steel drum and electrically connected to an electronic device continuously detects and picks up AC analog electrical signals and / or DC analog electrical signals. The electronic device integrates the AC analog electrical signals and / or DC analog electrical signals in the time dimension and determines the integrated result as the aforementioned analog signal.

[0056] Based on the control requirements of the high-voltage control system, a target signal is determined and acquired through the aforementioned acquisition device. Then, the target signal is integrated in the time dimension through electronic equipment, and the integrated result is determined as an analog signal. The target signal can be associated with the initial electrostatic field from at least one of the time dimension, amplitude dimension, and signal type dimension. The control requirements may include the voltage control accuracy of the high-voltage control system and / or the stability of the final controlled voltage.

[0057] Step 102: Determine the first digital signal corresponding to the analog signal.

[0058] In one implementation, the first digital signal can be obtained by quantizing an analog signal; for example, the analog signal can be converted by an A / D conversion circuit to obtain the first digital signal.

[0059] Step 103: Determine the adjustment strategy based on the degree of difference between the first digital signal and the second digital signal.

[0060] In one embodiment, the second digital signal may include at least one type of digital signal pre-configured in the electronic device.

[0061] In one implementation, the second digital signal may be predetermined according to control requirements; for example, the control requirements may include at least one of the requirements for voltage control accuracy, voltage control amplitude, and voltage control stability; for example, the second digital signal may include a digital electrical signal having a specified accuracy, a specified amplitude, or a specified stability.

[0062] In one embodiment, the degree of difference may include the degree of difference between the types of digital signals contained in the first digital signal and the second digital signal, and may also include the degree of difference between the amplitudes of the digital signals contained in the first digital signal and the second digital signal.

[0063] In one implementation, the tuning strategy may include at least one of the following: how to adjust the initial voltage, conditions, timing, and duration of adjustment.

[0064] In one implementation, the adjustment strategy can be determined in the following way:

[0065] An adjustment strategy is determined based on the matching relationship between the degree of differentiation in the correlation and the aforementioned degree of differentiation; wherein, the correlation may include a one-to-one correspondence between a predetermined degree of differentiation and a strategy; the aforementioned degree of differentiation may be preset, and the aforementioned degree of differentiation may include the degree of differentiation between a pre-detected digital signal and a pre-set digital signal.

[0066] Step 104: Based on the adjustment strategy, adjust the initial voltage to obtain the target voltage, so as to adjust the beam parameters of the initial beam ejected from the beam channel through the target voltage.

[0067] In one implementation, the target voltage may be different from the initial voltage.

[0068] In one implementation, the target voltage can be either analog or digital.

[0069] In one implementation, the target voltage can be obtained by adjusting it in any of the following ways:

[0070] The target voltage is obtained by adjusting the amplitude of the initial voltage based on the amplitude adjustment parameters corresponding to the adjustment strategy; for example, the amplitude adjustment parameters may include parameters that increase or decrease the amplitude of the initial voltage.

[0071] Within the time or period corresponding to the timing parameters of the adjustment strategy, the initial voltage is adjusted to obtain the target voltage.

[0072] In one embodiment, the beam parameters may include the directionality parameters of the initial beam; for example, the directionality parameters may characterize the degree of concentration of the initial beam.

[0073] In one embodiment, the initial electrostatic field inside the steel drum can be adjusted to the target electrostatic field by setting the target voltage between the high-voltage end and the low-voltage end of the steel drum, and the beam parameters of the initial beam can be adjusted by the field strength of the target electrostatic field.

[0074] As can be seen from the above, the voltage adjustment method for a high-voltage control system provided in this application embodiment acquires at least an analog signal associated with the initial electrostatic field set in the steel drum, and the analog signal includes AC analog electrical signals and / or DC analog electrical signals. The initial electrostatic field is associated with the initial voltage configured in the steel drum. Thus, through the above operations, real-time acquisition of the analog signal indirectly associated with the initial voltage configured in the steel drum can be achieved. Furthermore, by determining the first digital signal corresponding to the analog signal, digital conversion processing of the analog signal is realized, thereby reducing the complexity of storing and processing the analog signal. Based on this, based on the first digital signal... The degree of difference between the first and second digital signals determines the adjustment strategy, thus directly linking the adjustment strategy determination process with the first and second digital signals. This reduces the complexity of determining the adjustment strategy and makes it possible to determine the adjustment strategy automatically and intelligently through electronic devices. Furthermore, leveraging the advantages of the first and second digital signals in storage and / or computation, the flexibility of adjustment strategy determination is improved. This allows for the adjustment of the initial beam parameters of the beam channel by adjusting the target voltage obtained from the initial voltage based on the adjustment strategy, thereby meeting actual beam parameter control requirements. In summary, the voltage adjustment method for high-voltage control systems provided in this application, by determining the adjustment strategy based on the first and second digital signals, simplifies the adjustment strategy determination process, improves the speed and flexibility of initial voltage adjustment, and enhances the accuracy of the adjustment strategy, thereby meeting actual voltage adjustment requirements.

[0075] Based on the foregoing embodiments, in the voltage adjustment method provided in this application, the steel barrel and the corona needle are associated; the adjustment strategy includes a strategy for adjusting the setting method of the corona needle.

[0076] In one embodiment, the corona needle may be at least partially disposed inside the steel drum.

[0077] In one embodiment, the corona needle can be made of metal, and its tip, which is disposed inside the steel drum, can generate a corona current under the action of the electrostatic field inside the steel drum. For example, by adjusting the magnitude of the corona current, the amplitude of the initial voltage can be indirectly adjusted. For example, the electrostatic field inside the steel drum can include an initial electrostatic field and a target electrostatic field.

[0078] In one embodiment, adjusting the setting method of the corona needle may include adjusting the setting position of the corona needle and replacing the corona needle; for example, replacing the corona needle may include changing from a corona needle with a first parameter to a corona needle with a second parameter; for example, the first parameter and the second parameter may include at least one parameter among material, geometry and size.

[0079] Accordingly, the adjustment strategy is determined based on the degree of difference between the first digital signal and the second digital signal, which can be achieved through the following steps:

[0080] Step A1: Amplify the first digital signal to obtain the amplified signal.

[0081] In one implementation, the first digital signal can be amplified using a proportional-integral-differential (PID) amplifier circuit to obtain an amplified signal, thereby improving the stability of the amplified signal.

[0082] Step A2: Determine the degree of difference between the k-th signal in the amplified signal and the k-th signal in the second digital signal.

[0083] Where k is an integer greater than or equal to 1 and less than or equal to K; K is the number of signals contained in the first digital signal.

[0084] In one implementation, the k-th signal in the amplified signal and the k-th signal in the second digital signal can have the same signal type. For example, the k-th signal in the amplified signal and the k-th signal in the second digital signal can both be voltage signals.

[0085] In one implementation, the difference between the amplitude of the k-th signal in the amplified signal and the amplitude of the k-th signal in the second digital signal can be determined as the k-th difference level.

[0086] In one implementation, the number of signals contained in the second digital signal may be greater than or equal to the number of signals contained in the amplified signal.

[0087] In one implementation, the type of signal contained in the second digital signal may be the same as or different from the type of signal contained in the amplified signal.

[0088] Step A3: Based on the first to the Kth degree of difference, determine the strategy for adjusting the setting of the corona needle.

[0089] In one implementation, the strategy for adjusting the setting of the corona needle can be determined in the following way:

[0090] Based on the relative strengths of the K degrees of difference represented by the first degree of difference and the Kth degree of difference, a strategy for adjusting the setting of the corona needle is determined. For example, if each of the K degrees of difference is greater than or equal to the difference threshold, the setting of the corona needle can be adjusted according to the first method. If each of the K degrees of difference is less than the difference threshold, the setting of the corona needle can be adjusted according to the second method. The adjustment range corresponding to the first method can be greater than the adjustment range corresponding to the second method.

[0091] As can be seen from the above, the voltage adjustment method provided in this application reduces the complexity of subsequent processing circuits by amplifying the first digital signal to obtain the amplified signal; furthermore, by measuring the degree of difference between the kth signal in the amplified signal and the kth signal in the second digital signal, the degree of difference between the amplified signal and the second digital signal among multiple and / or multiple types of signals can be comprehensively reflected; at the same time, the strategy of determining the setting method of the corona needle based on the first degree of difference to the kth degree of difference can improve the accuracy and comprehensiveness of the above strategy.

[0092] Based on the foregoing embodiments, in the voltage adjustment method provided in this application, the steel barrel and the corona needle are associated.

[0093] Accordingly, the adjustment strategy is determined based on the degree of difference between the first digital signal and the second digital signal, which can be achieved in the following way:

[0094] If the amplitude of the first digital signal is less than the amplitude of the second digital signal, the adjustment strategy is determined as follows: extend the insertion length of the corona needle into the steel barrel.

[0095] For example, if the amplitude of the first digital signal is greater than or equal to the amplitude of the second digital signal, the operation of determining the adjustment strategy to extend the insertion length of the corona needle into the steel barrel may not be performed.

[0096] In one embodiment, the amplitude of the first digital signal is smaller than the amplitude of the second digital signal, which may include the amplitude of the k-th signal in the first digital signal or the amplified signal corresponding to the first digital signal being smaller than the amplitude of the k-th signal in the second digital signal.

[0097] In one embodiment, the insertion length may include the setting point of the corona needle on the inner surface of the steel drum and the distance between the setting point and the tip of the corona needle.

[0098] In one embodiment, the corona needle and the steel drum can be movably connected. In this case, after determining the above-mentioned adjustment strategy, the insertion length of the corona needle into the steel drum can be extended based on the adjustment strategy.

[0099] As can be seen from the above, in the voltage adjustment method provided in this application embodiment, if the amplitude of the first digital signal is less than the amplitude of the second digital signal, the adjustment strategy is determined to be: extending the insertion length of the corona needle into the steel drum. Thus, through the above operations, direct control of the insertion length of the corona needle based on the first and second digital signals is achieved, thereby simplifying the voltage adjustment method for the steel drum and realizing flexible indirect control of the voltage set on the steel drum by adjusting the insertion length of the corona needle.

[0100] Based on the foregoing embodiments, in the voltage adjustment method provided in this application, the steel barrel and the corona needle are associated.

[0101] Accordingly, the adjustment strategy can also be determined based on the degree of difference between the first digital signal and the second digital signal, and can be implemented in the following ways:

[0102] If the amplitude of the first digital signal is greater than the amplitude of the second digital signal, the adjustment strategy is determined as follows: shorten the insertion length of the corona needle into the steel barrel.

[0103] For example, if the amplitude of the first digital signal is equal to the amplitude of the second digital signal, the adjustment strategy can be determined as: maintaining the current insertion length of the corona needle.

[0104] For example, if the amplitude of the first digital signal is less than the amplitude of the second digital signal, the adjustment strategy can be determined by the method provided in the foregoing embodiments: extending the insertion length of the corona needle.

[0105] In one embodiment, the amplitude of the first digital signal is greater than the amplitude of the second digital signal, which may include the amplitude of the k-th signal in the first digital signal or the amplified signal corresponding to the first digital signal being greater than the amplitude of the k-th signal in the second digital signal.

[0106] As can be seen from the above, in the voltage adjustment method provided in this application embodiment, if the amplitude of the first digital signal is greater than the amplitude of the second digital signal, the adjustment strategy is determined to be: shortening the insertion length of the corona needle into the steel drum. Thus, through the above operation, direct control of the insertion length of the corona needle based on the first and second digital signals is achieved, thereby simplifying the voltage adjustment method for the steel drum and realizing flexible indirect control of the voltage set on the steel drum by adjusting the insertion length of the corona needle.

[0107] Based on the foregoing embodiments, in the voltage adjustment method provided in this application, the analog signal includes a first voltage signal.

[0108] Accordingly, obtaining at least the analog signal associated with the initial electrostatic field in the steel drum can be achieved through the following steps:

[0109] Step B1: Detect the first initial signal using a GVM set on the inner surface of the steel drum.

[0110] In one implementation, the first initial signal may be an AC signal type.

[0111] In one embodiment, the GVM can detect and acquire a first initial signal by the change in the positional relationship between its fixed plate and moving plate. For example, both the fixed plate and the moving plate can be made of metal, and the moving plate can perform uniform rotation around the fixed plate. When the GVM is in the initial electrostatic field, through the above-mentioned uniform rotation, when the fixed plate is exposed to the initial electrostatic field, the induced charge on its surface begins to accumulate. When the fixed plate is blocked by the moving plate, the induced charge accumulated on the surface of the fixed plate can be discharged through an integrating circuit to obtain the first initial signal of AC type.

[0112] In one implementation, the first initial signal may be a voltage-type signal.

[0113] Step B2: Shape the first initial signal to obtain the first voltage signal.

[0114] In one embodiment, the first initial signal can be shaped by a shaping circuit or a filtering circuit to obtain a first voltage signal.

[0115] In one implementation, the first voltage signal can be a DC signal type.

[0116] It should be noted that in practical applications, the number of fixed and moving blades and / or the blade area of ​​the GVM can be adjusted according to control requirements, thereby adjusting the amplitude of the first initial signal.

[0117] As can be seen from the above, the voltage adjustment method provided in this application embodiment detects a first initial signal using a GVM (Gas Dynamic Monitor) installed on the inner surface of the steel drum, and then shapes the first initial signal to obtain a first voltage signal. Thus, in the above operation, the detection operation of the GVM improves the stability of the detected first initial signal, thereby reducing the probability of arbitrary fluctuations in the first initial signal and the first voltage signal, and consequently improving the accuracy of the first initial signal and the first voltage signal.

[0118] Based on the foregoing embodiments, in the voltage adjustment method provided in this application, the analog signal includes a second voltage signal.

[0119] Accordingly, at least the analog signal associated with the initial electrostatic field in the steel drum can be obtained in the following way:

[0120] Obtain the second voltage signal output by the CPU board located in the steel drum.

[0121] The change in the second voltage signal is related to the change in the initial electrostatic field.

[0122] In one implementation, the CPU board can be pre-installed on the inner surface of the steel drum.

[0123] In one embodiment, the change in the initial voltage inside the steel drum causes a change in the initial electrostatic field inside the steel drum. Thus, when the initial electrostatic field changes, the number of induced charges on the surface of the CPU board also changes. With the capacitance of the CPU board fixed, the change in the number of induced charges on its surface will inevitably cause a change in the voltage on the CPU board. The voltage in the aforementioned changing state can be a second voltage signal.

[0124] In practical applications, even a slight change in the initial voltage will cause a change in the amount of induced charge on the surface of the CPU board. Therefore, the CPU board can quickly and accurately detect the second voltage signal.

[0125] As can be seen from the above, in the voltage adjustment method provided in this application embodiment, a second voltage signal output by the CPU board installed in the steel drum is acquired, and the change state of the second voltage signal is correlated with the change state of the initial electrostatic field. Thus, by utilizing the high sensitivity of the CPU board to induced charges, the accuracy of the second voltage signal can be improved; furthermore, since the CPU board can quickly detect the change state of its induced charges, the detection efficiency of the second voltage signal can also be improved through the above operations.

[0126] Based on the foregoing embodiments, in the voltage adjustment method provided in this application, the analog signal includes a third voltage signal.

[0127] In one implementation, the beam channel can eject an initial beam containing a specified number of particles at a certain speed.

[0128] Accordingly, obtaining at least the analog signal associated with the initial electrostatic field in the steel drum can also be achieved in the following ways:

[0129] The second initial signal is acquired by the grating of the slit instrument; the second initial signal is amplified to obtain the third voltage signal.

[0130] The second initial signal is associated with at least a portion of the particles in the processed beam output from the steel drum; the processed beam is associated with the initial beam; and a slit meter is used to process the processed beam.

[0131] In one embodiment, the processed beam can be obtained by processing the initial beam through an initial high voltage set in a steel drum.

[0132] In one implementation, the beam direction, velocity, and number of particles contained in the processed beam may differ from at least one of the beam direction, velocity, and number of particles contained in the initial beam.

[0133] In one embodiment, a slit meter can be used to perform beam direction conversion processing on the processed beam.

[0134] In one embodiment, gratings can be disposed on both sides of the object slit of the slit instrument to capture at least a portion of the particles in the processing beam that have not passed through the object slit; wherein, after the steel barrel processes the initial beam to obtain the processed beam, the processed beam can be output to the slit instrument.

[0135] In one implementation, the intensity of the second initial signal may be related to the number and / or velocity of at least some of the particles.

[0136] In one implementation, the second initial signal can be amplified by a power amplifier to obtain the third voltage signal.

[0137] As can be seen from the above, the voltage adjustment method provided in this application obtains a second initial signal through the grating acquisition of the slit instrument, and the second initial signal is associated with at least a portion of the particles in the processed beam output by the steel barrel. The processed beam processed by the slit instrument is associated with the initial beam. Thus, through the above operation, the second initial signal can be associated with the processing effect of the steel barrel on the initial beam from the dimension of at least a portion of the particles. Furthermore, by amplifying the second initial signal to obtain a third voltage signal, the complexity of the subsequent circuit for processing the third voltage signal can be simplified.

[0138] Based on the foregoing embodiments, the voltage adjustment method provided in this application, which amplifies the second initial signal to obtain the third voltage signal, can be achieved in the following way:

[0139] The second initial signal is converted into a voltage signal type; the converted second initial signal is differentially amplified to obtain the third voltage signal.

[0140] In one implementation, the second initial signal may be a current signal type.

[0141] In one implementation, the second initial signal can be converted by a preamplifier to obtain a second initial signal of the voltage signal type.

[0142] In one implementation, a third voltage signal can be obtained by differentially amplifying the second initial signal, which has been converted into a voltage signal type, using a differential amplifier.

[0143] As can be seen from the above, in the voltage adjustment method provided in this application embodiment, the second initial signal is converted into a voltage signal type, and the converted second initial signal is differentially amplified to obtain a third voltage signal. Thus, through the above operations, synchronous processing of the signal type and differential amplification of the second initial signal is achieved, thereby improving the anti-interference capability and transmission stability of the third voltage signal.

[0144] Figure 2 This is a schematic diagram of the structure of the voltage adjustment method provided in the embodiments of this application, as shown below. Figure 2 As shown, this method can be implemented using the following modules or units:

[0145] An initial voltage can be set between the high-voltage end and the low-voltage end of the steel drum 201. An initial electrostatic field corresponding to the initial voltage can exist inside the steel drum 201. Furthermore, a GVM 202, a CPU board 203, and a beam channel can also be set inside the steel drum 201.

[0146] For example, the first voltage signal can be detected or acquired by means of the fixed and moving plates set in GVM 202 using the method provided in the foregoing embodiments.

[0147] For example, the second voltage signal can be detected or acquired by means of the CPU board 203 using the method provided in the foregoing embodiments.

[0148] For example, a second initial signal can be obtained by detecting at least a portion of the particles in the beam through a grating included in a slit meter 204 associated with the steel barrel 201, and the second initial signal can be converted and amplified to obtain a third voltage signal.

[0149] It should be noted that in actual voltage adjustment operations, at least two modules among GVM 202, CPU board 203 and gap meter 204 can be selected to detect the corresponding voltage signal.

[0150] For example, the first voltage signal, the second voltage signal, and the third voltage signal can be converted into analog signals by analog-to-digital converter 205, respectively, so as to obtain the first signal, the second signal, and the third signal, and the set of the above signals is determined as the first digital signal.

[0151] For example, the PID 206 can be used to amplify each signal in the first digital signal to obtain the corresponding amplified signal.

[0152] For example, the adjustment strategy for the corona needle set in the steel barrel 201 can be determined by comparing the degree of difference between the amplified signal and the signal in the preset second digital signal by the comparison circuit 207.

[0153] For example, if the amplitude of the amplified signal is greater than the amplitude of the second digital signal, the adjustment strategy can be determined as: shortening the insertion length of the corona needle.

[0154] For example, if the amplitude of the amplified signal is less than the amplitude of the second digital signal, the adjustment strategy can be determined as: extending the insertion length of the corona needle.

[0155] For example, the probe length determined by the above method can be a digital signal. In this case, the probe length can be converted into an analog signal by the analog-to-digital converter 208, and the probe length of the corona needle set in the steel barrel 201 can be controlled based on the probe length converted into an analog signal, thereby achieving the purpose of adjusting the amplitude of the corona current at the tip of the corona needle, and thus achieving the adjustment of the initial voltage in the steel barrel 201.

[0156] Through the cooperation of the various modules or units mentioned above, real-time detection of the voltage signal corresponding to the electrostatic field inside the steel drum can be achieved. Furthermore, the electrical signals obtained through the GVM, CPU board, or gap meter are all voltage signals, which reduces the requirements for analog-to-digital conversion and improves the efficiency of analog-to-digital conversion and subsequent comparison operations of the comparison circuit.
