[0002] In controlled nuclear fusion research, plasma radiation is an important energy loss channel. Especially in high-parameter discharge conditions, various instabilities in the plasma may discharge a large amount of particles and heat, such as edge localized modes in high confinement modes, instantaneous high heat discharge caused by various magnetohydrodynamic instabilities, and conventional high heat flux in divertors under high-parameter steady-state discharges. In order to reduce the impact of these high heat loads on the plasma-facing materials of the device, actively dissipating energy through radiation is a common approach. Therefore, the control of plasma radiation is a control technology of great significance.

DETAILED DESCRIPTION

[0057] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0058] like Figure 1 As shown, an embodiment of the present invention provides a fusion device plasma radiation regulation system, including a radiation array measurement unit 200, a storage unit 300, a central processing unit 400 and an actuator 500;

[0059] The radiation array measurement unit 200 is used to measure the radiation signal image corresponding to the plasma 100 of the fusion device, and transmit the measured radiation signal image to the storage unit 300;

[0060] The storage unit 300 is used to receive the radiation signal image transmitted by the radiation array measurement unit 200, store the radiation signal image, and provide data support for the central processing unit 400;

[0061] The central processing unit 400 is used to obtain the radiation signal image in the storage unit 300, and determine the feedback control parameters according to the preset target radiation distribution and the radiation signal image, and finally transmit the feedback control parameters to the actuator 500;

[0062] The actuator 500 is used to receive feedback control parameters and adjust the fusion device according to the feedback control parameters to adjust the radiation distribution corresponding to the plasma 100.

[0063] In a possible implementation, the central processing unit 400 includes a signal processing subunit 410, an actuator parameter calculation subunit 420, and an actuator control signal output subunit 430;

[0064] The signal processing subunit 410 is used to obtain the radiation signal image in the storage unit 300, and obtain the difference between the preset target radiation distribution and the radiation signal image. When the difference is greater than zero, the feedback control task is triggered, and the actuator parameter calculation subunit 420 and the actuator control signal output subunit 430 are scheduled to perform the feedback control task;

[0065] The actuator parameter calculation subunit 420 is used to obtain the distribution parameters of the actuator injected gas according to the difference between the preset target radiation distribution and the radiation signal image, and determine the feedback control parameters according to the distribution parameters of the actuator injected gas;

[0066] The actuator control signal output subunit 430 is used to output the feedback control parameters output by the actuator parameter calculation subunit 420 to the actuator 500 .

[0067] Optionally, the control process is described in detail in the embodiment of the present invention, as follows.

[0068] 1. The plasma background radiation is higher than the target radiation value, that is, the difference is less than zero.

[0069] The plasma 100 releases radiation, and the radiation array measurement unit 200 measures the radiation signal image and transmits the information to the storage unit 300. The signal is then transmitted to the central processing unit 400. The signal processing subunit 410 in the central processing unit processes the signal and calculates the input target radiation distribution through the actuator parameter calculation unit 420. If the target radiation distribution is lower than the radiation distribution obtained by measurement and processing, that is, there is no need for radiation enhancement, the actuator control parameter output unit 430 does not output a signal, and the system terminates and does not work.

[0070] 2. Control of radiation distribution on the weak field side of plasma.

[0071] The plasma 100 releases radiation, and the radiation array measurement unit 200 measures the radiation signal image and transmits the information to the storage unit 300. The signal is then transmitted to the central processing unit 400. The signal processing subunit 410 in the central processing unit processes the signal and calculates the input target radiation distribution through the actuator parameter calculation unit 420.

[0072] If the target radiation distribution on the weak field side is higher than the radiation distribution obtained by processing, the control system needs to be started to enhance the radiation on the weak field side. The actuator parameter calculation unit 420 calculates the distribution of the gas to be injected into the actuator according to the radiation distribution difference, mainly including the beam divergence angle α and the effective distance X MTwo parameters (among which, the minimum effective distance should be the minimum distance from the injector port to the plasma boundary, and the divergence angle refers to twice the angle between the tangent line of the barrel-shaped shock wave surface of the injector port and the central axis of the injector), and the multivariate indeterminate equation is solved for the control parameters. The control parameters mainly include the gas source pressure P0 (0.5bar-30bar), the background pressure P b (10 -2 -100Pa), injector aperture d (0.1mm-3mm), and expansion section length L (0-30mm). In this system, the injector cone angle is fixed at 180 degrees. If it is other angles, one more variable can be added to solve.

[0073]

[0074] α=0.013×d 0.14 L -0.82 p0 0.2 p b -0.08

[0075] When solving, the current aperture d and expansion section length L are given priority as fixed values, and the gas source pressure and background pressure are directly calculated. When the solution value exceeds the range, the aperture and expansion section length L are changed in turn to solve until the first set of control parameters that meet the requirements [P 01 ,P b1 ,d1,L1], outputs the actuator control parameter group to the actuator 500 through the actuator control parameter output unit 430.

[0076] At this time, the radiation on the weak field side needs to be enhanced, so the weak field side actuator starts to act, and the weak field side controller 510 outputs a signal to adjust the various components of the actuator structure. The pressure control valve 520 adjusts the pressure at the gas source end to P according to the pressure control signal transmitted by the weak field side controller 510. 01 The vacuum pump 530 adjusts the background pressure to P according to the vacuum control signal transmitted by the controller 510 b1 ; The slide rail 540 adjusts the slide rail position to L1 according to the slide rail position signal transmitted by the controller 510; the rotary shutter 550 adjusts the rotary shutter size to d1 according to the aperture signal transmitted by the controller 510; in particular, if the original state of each component is consistent with the target state given by the control signal, that is, the actuator component does not operate.

[0077] 3. Control of radiation distribution on the strong field side of plasma.

[0078] The plasma 100 releases radiation, and the radiation array measurement unit 200 measures the radiation signal image and transmits the information to the storage unit 300. The signal is then transmitted to the central processing unit 400. The signal processing subunit 410 in the central processing unit processes the signal and calculates the input target radiation distribution through the actuator parameter calculation unit 420.

[0079] If the target radiation distribution on the strong field side is higher than the radiation distribution obtained by processing, the control system needs to be started to enhance the radiation on the strong field side. The actuator parameter calculation unit 420 calculates the distribution of the gas to be injected into the actuator according to the radiation distribution difference, mainly including the beam divergence angle α and the effective distance X M Two parameters, and solve the multivariate indeterminate equation for the control parameters. The control parameters mainly include the gas source pressure P0 (0.5bar-30bar), the background pressure P b (10 -2 -100Pa), injector aperture d (0.1mm-3mm), and expansion section length L (0-30mm). In this system, the injector cone angle is fixed at 180 degrees. If it is other angles, one more variable can be added to solve.

[0080]

[0081] α=0.013×d 0.14 L -0.82 p0 0.2 p b -0.08

[0082] When solving, the current aperture d and expansion section length L are given priority as fixed values, and the gas source pressure and background pressure are directly calculated. When the solution value exceeds the range, the aperture and expansion section length L are changed in turn to solve until the first set of control parameters that meet the requirements [P 01 ,P b1 ,d1,L1], outputs the actuator control parameter group to the actuator 500 through the actuator control parameter output unit 430.

[0083] At this time, the radiation on the strong field side needs to be enhanced, so the strong field side actuator starts to act, and the strong field side controller 510 outputs a signal to adjust the various components of the actuator structure. The pressure control valve 520 adjusts the pressure at the gas source end to P according to the pressure control signal transmitted by the controller 510. 01 The vacuum pump 530 adjusts the background pressure to P according to the vacuum control signal transmitted by the controller 510 b1; The slide rail 540 adjusts the slide rail position to L1 according to the slide rail position signal transmitted by the controller 510; the rotary shutter 550 adjusts the rotary shutter size to d1 according to the aperture signal transmitted by the controller 510; in particular, if the original state of each component is consistent with the target state given by the control signal, that is, the actuator component does not operate.

[0084] Optionally, the strong field side controller and the weak field side controller may be the same controller or different controllers, and both implementations may implement the functions described in the embodiments of the present invention.

[0085] 4. Control of the strength and weakness of plasma radiation distribution.

[0086] The plasma 100 releases radiation, and the radiation array measurement unit 200 measures the radiation signal image and transmits the information to the storage unit 300. The signal is then transmitted to the central processing unit 400. The signal processing subunit 410 in the central processing unit processes the signal and calculates the input target radiation distribution through the actuator parameter calculation unit 420.

[0087] If the target radiation distribution on both the weak and strong field sides is higher than the radiation distribution obtained by processing, the control system needs to be started and the radiation on the weak and strong field sides needs to be enhanced. The actuator parameter calculation unit 420 calculates the distribution of the gas to be injected by the actuator according to the radiation distribution difference, mainly including the beam divergence angle α and the effective distance X M Two parameters, and solve the multivariate indeterminate equation for the control parameters. The control parameters mainly include the gas source pressure P0 (0.5bar-30bar), the background pressure P b (10 -2 -100Pa), injector aperture d (0.1mm-3mm), and expansion section length L (0-30mm). In this system, the injector cone angle is fixed at 180 degrees. If it is other angles, one more variable can be added to solve.

[0088]

[0089] α=0.013×d 0.14 L -0.82 p0 0.2 p b -0.08

[0090] When solving, the current aperture d and expansion section length L are given priority as fixed values, and the gas source pressure and background pressure are directly calculated. When the solution value exceeds the range, the aperture and expansion section length L are changed in turn to solve until the first set of control parameters that meet the requirements [P 01 ,P b1,d1,L1], outputs the actuator control parameter group to the actuator 500 through the actuator control parameter output unit 430.

[0091] At this time, the radiation on the weak / strong field side needs to be enhanced, so the weak / strong field side actuators all start to act, and the strong field side controller 510 outputs a signal to adjust the various components of the actuator structure. The pressure control valve 520 adjusts the pressure at the gas source end to P according to the pressure control signal transmitted by the controller 510. 01 The vacuum pump 530 adjusts the background pressure to P according to the vacuum control signal transmitted by the controller 510 b1 ; The slide rail 540 adjusts the slide rail position to L1 according to the slide rail position signal transmitted by the controller 510; the rotary shutter 550 adjusts the rotary shutter size to d1 according to the aperture signal transmitted by the controller 510; in particular, if the original state of each component is consistent with the target state given by the control signal, that is, the actuator component does not operate.

[0092] 5. Fine control of plasma radiation distribution.

[0093] Fine control of plasma radiation distribution, that is, adding actuators at more plasma positions besides the weak / strong field side. The more actuators there are, the more fine distribution control can be achieved in theory.

[0094] In a possible implementation, obtaining a difference between a preset target radiation distribution and a radiation signal image includes: obtaining a strong field side radiation difference and / or a weak field side radiation difference between the preset target radiation distribution and the radiation signal image;

[0095] The feedback control parameters include strong field feedback control parameters obtained according to the strong field side radiation difference and / or weak field feedback control parameters obtained according to the weak field side radiation difference.

[0096] In a possible implementation, the actuator 500 includes a controller 510, a strong field radiation adjustment component, and a weak field radiation adjustment component;

[0097] The controller 510 is used to control the action of the strong field radiation adjustment component and / or the weak field radiation adjustment component according to the strong field feedback control parameter and / or the weak field feedback control parameter;

[0098] The strong field radiation adjustment component is used to respond to the control of the controller 510 to adjust the strong field radiation;

[0099] The weak field radiation adjustment component is used to respond to the control of the controller 510 to adjust the weak field radiation.

[0100] The controller 510 may include a strong field controller and a weak field controller. The strong field controller controls the strong field radiation adjustment component (ie, the strong field actuator), and the weak field controller controls the weak field radiation adjustment component (ie, the weak field actuator).

[0101] In a possible implementation, the strong field radiation adjustment component and the weak field radiation adjustment component have the same structure, and both adjust radiation through a pressure control valve 520 , a plurality of air pumps 530 , a slide rail 540 and a rotating shutter 550 .

[0102] like Figure 2 as well as Figure 3 As shown together, in order for those skilled in the art to further understand the technical concept of the present invention, an embodiment of the present invention provides a structural example of a strong field radiation adjustment component and a weak field radiation adjustment component, i.e., an actuator. The distributed control system actuator in the schematic diagram is represented by two positions, strong and weak, which respectively represent the two injection positions on the strong field side and the weak field side of the plasma. The actual system has more positions according to demand, thereby achieving more refined radiation distribution control at different positions. The number of vacuum pumps 530 can be reduced or increased according to actual needs, and each vacuum position can be controlled by an independent pump, or different vacuum positions can be connected to the same pump, but the opening and closing of different suction ports can be controlled independently. Figure 2 The front end of the slide rail 540 where the middle rotary shutter 550 is located is the gas supply port, and the corresponding interval of the vacuum pump is closed to ensure that the gas source pressure is controlled by the pressure control valve 520. The rear end is the injector port, which is connected to the plasma, and the vacuum degree is controlled by the vacuum pump 530 in this interval. If the rotary shutter is in position A, the vacuum pumps 1-6 can all be turned on; if the rotary shutter is in position B, the vacuum pumps 1-3 are closed, and 4-6 can be turned on; if the rotary shutter is in position C, the vacuum pumps 1-5 are all closed, and the vacuum pump 6 can be turned on; it is worth noting that the movement interval of the slide rail 540 is between positions A and C, and at least one vacuum pump is guaranteed to be located at the gas injection port end for the control of the background gas pressure Pb.
