Ion cyclotron antenna device

Abstract

This application relates to an ion cyclotron antenna device, including a controller; a detection component electrically connected to the controller, the detection component being used to detect the direction of the magnetic field in real time; a rotating device electrically connected to the controller; and an ion cyclotron antenna connected to the rotating device. When the direction of the magnetic field changes, causing the magnetic field direction to no longer be perpendicular to the ion cyclotron antenna, the detection component immediately feeds back a signal to the controller. The controller compares the relative positional relationship between the antenna and the magnetic field, and then outputs a command to the rotating device, enabling the rotating device to drive the ion cyclotron antenna to rotate and adjust, so that the ion cyclotron antenna is once again perpendicular to the direction of the magnetic field. Through the coordinated work of the detection component, the rotating device, and the controller, the relative perpendicularity between the ion cyclotron antenna and the direction of the magnetic field can always be guaranteed, thereby effectively suppressing the generation of parallel electric fields, reducing the generation of sheath potential, reducing the impact of high-energy particles on the antenna, and extending the steady-state operation time of the antenna and the nuclear fusion device.

Description

Technical Field

[0001] This application relates to the technical field of magnetically confined ion cyclotron wave heated plasma antennas, and in particular to an ion cyclotron antenna device. Background Technology

[0002] The ion cyclotron heating system is one of the most important auxiliary heating systems in a magnetically confined nuclear fusion device, the tokamak. The ion cyclotron heating system excites fast magnetoacoustic waves (or fast waves) by generating high-frequency oscillating currents in the antenna current band. These fast waves propagate from the antenna located at the plasma edge to the plasma core and transfer energy to the plasma in the resonant layer.

[0003] In related technologies, when a magnetic field acts on an ion cyclotron antenna at a non-perpendicular angle, it will lead to the generation of a parallel electric field, which in turn will cause the generation of sheath potential, increasing the impact of high-energy particles on the antenna and affecting the steady-state operation time of the antenna and nuclear fusion device. Summary of the Invention

The controller compares the relative position relationship between the antenna and the magnetic field and then outputs a command to the rotating device, enabling the rotating device to drive the ion cyclotron antenna to rotate and adjust so that the ion cyclotron antenna is once again perpendicular to the direction of the magnetic field. That is, with the help of the coordinated work of the detection component, the rotating device, and the controller, the relative perpendicular relationship between the ion cyclotron antenna and the direction of the magnetic field can always be guaranteed, thereby effectively suppressing the generation of parallel electric fields, thereby reducing the generation of sheath potential, thus reducing the impact of high-energy particles on the antenna, extending the steady-state operation time of the antenna and the nuclear fusion device, and providing support for the improvement of fusion power.

[0033] The ion cyclotron heating system is one of the most important auxiliary heating systems in a magnetically confined nuclear fusion device, the tokamak. The ion cyclotron heating system excites fast magnetoacoustic waves (fast waves) by generating a high-frequency oscillating current in the antenna current band. These fast waves propagate from the antenna located at the plasma edge to the plasma core, transferring energy to the plasma in the resonant layer. In related technologies, when a magnetic field acts on the ion cyclotron antenna 20 at a non-perpendicular angle, it leads to the generation of a parallel electric field, which in turn causes the sheath potential to increase the impact of high-energy particles on the antenna, affecting the steady-state operating time of the antenna and the nuclear fusion device.

[0034] For the above issues, please refer to Figure 1 This application discloses an ion cyclotron antenna device 100, which includes a controller, a detection component (not shown), a rotating device 10, and an ion cyclotron antenna 20. The controller is the control center of the entire device, used to realize the automated collaborative operation of the detection component, the rotating device 10, and the ion cyclotron antenna 20, thereby improving the intelligence level of the device.

[0035] For example, the controller can be, but is not limited to, a microcomputer, a PLC device, etc. The specific choice can be made flexibly according to actual needs, and no specific limitation is made here.

[0036] The detection component is electrically connected to the controller and is used to detect the direction of the magnetic field in real time; the rotating device 10 is electrically connected to the controller; and the ion cyclotron antenna 20 is connected to the rotating device 10.

[0037] In summary, implementing the technical solution of this embodiment will achieve the following beneficial effects: In the ion cyclotron antenna device 100 of this solution, by setting a detection component, the detection component can detect the direction of the magnetic field in the working environment in real time. When the direction of the magnetic field changes, causing the magnetic field direction to be no longer perpendicular to the ion cyclotron antenna 20, the detection component immediately feeds back a signal to the controller. The controller compares the relative position relationship between the antenna and the magnetic field, and then outputs a command to the rotating device 10, so that the rotating device 10 can drive the ion cyclotron antenna 20 to rotate and adjust, so that the ion cyclotron antenna 20 is perpendicular to the direction of the magnetic field again. That is, with the help of the coordinated work of the detection component, the rotating device 10 and the controller, the relative perpendicular relationship between the ion cyclotron antenna 20 and the direction of the magnetic field can always be guaranteed, thereby effectively suppressing the generation of parallel electric fields, thereby reducing the generation of sheath potential, thereby reducing the impact of high-energy particles on the antenna, extending the steady-state operation time of the antenna and the nuclear fusion device, and providing support for the improvement of fusion power.

[0038] Please continue reading. Figure 1In an optional embodiment, the rotating device 10 includes a base 11 and a first rotating power source 12. The first rotating power source 12 is mounted on the base 11, and the rotation axis of the first rotating power source 12 is connected to the ion cyclotron antenna 20 to drive the ion cyclotron antenna 20 to rotate in a first plane.

[0039] The base 11 is used to mount and support the first rotating power source 12 to ensure that the first rotating power source 12 outputs rotating power stably and reliably. During operation, under the command of the controller, the first rotating power source 12 can output precise rotating power to the ion cyclotron antenna 20 to drive the ion cyclotron antenna 20 to rotate at a suitable angle, ensuring that the ion cyclotron antenna 20 can always be perpendicular to the magnetic field direction through active adjustment.

[0040] For example, the first rotary power source 12 can be any of the following, such as an electric motor or a rotary cylinder, as long as it can stably output rotary power; no specific limitation is made here.

[0041] It should be noted that the first rotating power source 12 in this application is arranged in a horizontal position, that is, the center line of its rotation axis is in the horizontal direction, so it can drive the ion cyclotron antenna 20 to rotate clockwise or counterclockwise in a vertical plane, which is the first plane mentioned above.

[0042] Please continue reading. Figure 1 In another embodiment, the ion cyclotron antenna device 100 further includes a first transmission line 30 and a second transmission line 40. The first transmission line 30 is connected between the ion cyclotron antenna 20 and the rotation axis of the first rotating power source 12, and the second transmission line 40 is connected to the first transmission line 30 via a wiring channel on the rotation axis of the first rotating power source 12. The second transmission line 40 is used to connect to an external power source or signal source, allowing the ion cyclotron antenna 20 to obtain electrical energy supplied by the power source or a signal output from the signal source through the connected first transmission line 30 and second transmission line 40.

[0043] Please continue reading. Figure 1 and Figure 2 Furthermore, the ion cyclotron antenna device 100 also includes a connector 50 and a housing 60. The housing 60 has a mounting through hole 61, into which the connector 50 is inserted and connected to the second transmission line 40. The housing 60 is used to mount and fix the connector 50 to achieve stable installation. The connector 50 facilitates connection to an external power source or signal source, enabling the second transmission line 40 to be quickly and effectively connected to an external power source or signal source.

[0044] Optionally, the socket 50 can be any of the following: a two-hole socket, a three-hole socket, an aviation socket, etc., whichever is more suitable for the actual needs.

[0045] In order to precisely control the rotation angle of the ion cyclotron antenna 20 in the first plane and ensure that the magnetic field direction is perpendicular to the ion cyclotron antenna 20, in an optional embodiment, the rotating device 10 further includes a first angle sensor, which is disposed on the rotation axis of the first rotation power source 12.

[0046] Furthermore, based on any of the above embodiments, one of the ion cyclotron antenna 20 and the first transmission line 30 is provided with a locking body, and the other of the ion cyclotron antenna 20 and the first transmission line 30 is provided with a locking position, with the locking body and the locking position being connected by a snap-fit. On the one hand, by adopting the snap-fit ​​connection method of the locking body and the locking position, the ion cyclotron antenna 20 and the first transmission line 30 can be conveniently and quickly assembled and connected, reducing the installation difficulty and time consumption of the ion cyclotron antenna 20; on the other hand, by utilizing the holding force of the locking body and the locking position, the connection between the ion cyclotron antenna 20 and the first transmission line 30 is also improved, preventing them from easily loosening when subjected to external forces.

[0047] It should be noted that in some other optional embodiments, the ion cyclotron antenna 20 and the first transmission line 30 can also be fixed or detachably connected by any of the following methods: threaded connection, adhesive bonding, riveting, etc., and can be flexibly rotated according to actual needs.

[0048] Furthermore, considering that simply setting the first rotating power source 12 to drive the ion cyclotron antenna 20 to rotate in the first plane may not be able to meet the problem of maintaining perpendicularity to the magnetic field direction after rotation adjustment, in another embodiment, the rotating device 10 also includes a bracket 13 and a second rotating power source (not shown in the figure). The bracket 13 is mounted on the base 11, the second rotating power source is disposed on the bracket 13, and the rotation axis of the second rotating power source is connected to the first rotating power source 12 to drive the first rotating power source 12 and the ion cyclotron antenna 20 to rotate in the second plane; wherein, the second plane intersects the first plane.

[0049] Therefore, by adding a second rotational power source connected to the first rotational power source 12, the first rotational power source 12 and the ion cyclotron antenna 20 can be driven to rotate in the second plane. Since the second plane intersects with the first plane, the ion cyclotron antenna 20 has more rotational freedom and can be adjusted in more directions to meet the adjustment needs of the ion cyclotron antenna 20 to ensure that it is perpendicular to the magnetic field in different directions.

[0050] For example, the second rotational power source can be any of the following, such as an electric motor or a rotary cylinder, as long as it can stably output rotational power; no specific limitation is made here.

[0051] It should be noted that in actual operation, the first rotary power source 12 and the second selective power source can operate separately and sequentially, or they can operate simultaneously. The specific choice can be made flexibly according to actual needs, and no specific limitation is made here.

[0052] It should also be noted that, since the bracket 13 is installed on the base 11, the bracket 13 can lift the first rotary power source 12 through the second rotary power source, so that the first rotary power source 12 is at a preset height position above the base 11, so that the distance between the first rotary power source 12 and the base 11 can be used as the stroke space for the first rotary power source 12 to swing up and down, thus avoiding collision interference between the first rotary power source 12 and the base 11.

[0053] To precisely control the rotation angle of the ion cyclotron antenna 20 within the second plane and ensure that the magnetic field direction is perpendicular to the ion cyclotron antenna 20, in an optional embodiment, the rotating device 10 further includes a second angle sensor, which is disposed on the rotation axis of the second rotational power source. It is readily understood that by directly detecting the rotation angle of the rotation axis, the second angle sensor can indirectly and synchronously detect the rotation angle of the ion cyclotron antenna 20.

[0054] Furthermore, in one embodiment, the detection component includes a detection frame and a magnetic probe. The magnetic probe is mounted on the detection frame and used to detect the direction of the magnetic field in real time. Therefore, the detection frame can load and fix the magnetic probe, ensuring its stable positioning in the detection environment. The magnetic probe then detects the direction of the magnetic field in real time, providing feedback signal data to the controller. The controller then outputs commands to the first rotating power source 12 and / or the second rotating power source, driving the ion cyclotron antenna 20 to rotate and re-align with the magnetic field direction. This effectively suppresses the generation of parallel electric fields, thereby reducing the sheath potential and minimizing the impact of high-energy particles on the antenna. This extends the steady-state operating time of the antenna and the nuclear fusion device, while also supporting the increase of fusion power.

[0055] Please continue reading. Figure 1 and Figure 2 Based on any of the above embodiments, the ion cyclotron antenna device 100 further includes a connecting rod 70. At least two ion cyclotron antennas 20 are provided, and adjacent ion cyclotron antennas 20 are connected and fixed together by at least one connecting rod 70. By adding a connecting rod 70 between adjacent ion cyclotron antennas 20, the first rotating power source 12 can be simultaneously connected to at least two ion cyclotron antennas 20. The connecting rod 70 ensures the synchronicity of the movement of at least two ion cyclotron antennas 20, thereby enabling simultaneous synchronous adjustment of the angles of at least two ion cyclotron antennas 20.

[0056] Optionally, the connecting rod 70 has a U-shaped structure, which makes it easier to install with two adjacent ion cyclotron antennas 20. The installation method of the connecting rod 70 and the ion cyclotron antenna 20 can be any one of the following: screw connection, plug connection, snap connection, adhesive connection, magnetic connection, etc. The specific method can be flexibly selected according to actual needs, and no specific limitation is made here.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
