[0035] The technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments, not all embodiments.

[0036] Example

[0037] like Figures 1 to 6 As shown, this embodiment provides a beam merging system based on a dual-beam deflector, which includes a first solenoid 10, a second solenoid 20, and a dual-beam deflection device 30. In this embodiment, the beam output from the first solenoid 10 is deflected by the dual-beam deflection device 30 and then merged into a single beam in the second solenoid 20, thus changing the two intersecting beams into one, achieving the purpose of beam merging.

[0038] Specifically, two first solenoids 10 are configured and arranged in parallel, each having a first beam channel 11. A second solenoid 20 has a second beam channel 21. The two first beam channels 11 are parallel. The first solenoids 10 and 20 are primarily used to confine the passing beam.

[0039] Specifically, the dual-beam deflection device 30 is disposed between the first solenoid 10 and the second solenoid 20, and the dual-beam deflection device 30 is configured to receive the beams emitted from the first solenoid 10 and the second solenoid 20.

[0040] Specifically, such as Figure 6 As shown, the dual-beam deflection device 30 has two third beam channels 34 that correspond one-to-one with the two first beam channels 11. The dual-beam deflection device 30 is used to deflect the two received beams toward the central axis of the second beam channel 21.

[0041] Specifically, the second solenoid 20 is used to merge the beams emitted from the two third beam channels 34.

[0042] In use, two parallel beams enter the system through two first solenoids 10. The beams pass through two parallel first beam channels 11 respectively. The beams are stably transmitted by the helical magnetic field of the first solenoids 10 and sent into the dual beam deflection device 30.

[0043] The two beams are deflected towards the central axis of the second beam channel 21 using a magnetic field. After being deflected by the dual-beam deflection device 30, the two beams are merged together in the second solenoid 20. The merged beam is then transmitted smoothly in the second solenoid 20 to ensure that the beam can be stably transmitted to the next accelerator system.

[0044] When the beam passes through the dual-beam deflection device 30, it is deflected under the action of the Lorentz force. By adjusting the direction of the magnetic field, beams carrying different types of charges are all deflected inward. The direction and strength of the magnetic fields of the first electromagnet group 31 and the second electromagnet group 32 can be controlled by the control device 33. Multi-directional control of the particle beam can be achieved, thereby improving the accuracy and stability of the particle beam.

[0045] It should be noted that the deflection angle and deflection direction of the dual-beam deflection device can be adjusted according to actual needs to achieve the best beam merging effect.

[0046] In this embodiment, both the first solenoid 10 and the second solenoid 20 are provided with a base 12. By providing a base, it is convenient for users to place the first solenoid 10 and the second solenoid 20, thereby improving the stability of the first solenoid 10 and the second solenoid 20.

[0047] In this embodiment, the dual-beam deflection device 30 includes a first electromagnet group 31, a second electromagnet group 32, and a control device 33. Both the first electromagnet group 31 and the second electromagnet group 32 are electrically connected to the control device 33. A third beam channel 34 is located within the first electromagnet group 31, and another third beam channel 34 is located within the second electromagnet group 32. A gap exists between the first electromagnet group 31 and the second electromagnet group 32.

[0048] Specifically, the first electromagnet group 31 includes a first N-pole electromagnet 311 and a first S-pole electromagnet 312. The first N-pole electromagnet 311 and the first S-pole electromagnet 312 are arranged opposite each other. A third beam channel is located between the first N-pole electromagnet 311 and the first S-pole electromagnet 312.

[0049] Specifically, the second electromagnet group 32 includes: a second N-pole electromagnet 321 and a second S-pole electromagnet 322.

[0050] The second N-pole electromagnet 321 and the second S-pole electromagnet 322 are arranged opposite each other.

[0051] Among them, the first N-pole electromagnet 311 and the second N-pole electromagnet 321 are diagonally distributed, and the first S-pole electromagnet 312 and the second S-pole electromagnet 322 are diagonally distributed.

[0052] Another third beam channel is located between the second N-pole electromagnet 321 and the second S-pole electromagnet 322.

[0053] In this embodiment, the second solenoid 20 is adjustablely positioned behind the dual-beam deflection device 30.

[0054] For example, a guide rail (not shown) is disposed below the second solenoid 20. The guide rail has two sliders. The base of the second solenoid 20 is fixedly connected to one of the sliders, and the bottom surface of the dual-beam deflection device 30 is fixedly connected to the other slider. The dual-beam deflection device 30 and the second solenoid 20 behind it adopt an adjustable connection structure, which can conveniently adjust the merging position and angle of the two beams, and has good flexibility.

[0055] In this embodiment, the first N-pole electromagnet, the first S-pole electromagnet, the second N-pole electromagnet, and the second S-pole electromagnet are made of permanent magnet materials or permanent magnet superconducting materials; the electromagnets have good magnetic field stability and can maintain a precise magnetic field distribution.

[0056] In another embodiment not shown, when the beam energy is particularly high, multiple dual-beam deflection devices 30 can be introduced in series to improve the beam merging effect and accuracy.

[0057] For example, two dual-beam deflection devices 30 are configured, and the two dual-beam deflection devices 30 are connected in series so that the central axes of at least two dual-beam deflection devices 30 coincide.

[0058] In another embodiment not shown, the dual-beam deflection device 30 further includes a housing. A first N-pole electromagnet 311 and a first S-pole electromagnet 312 are arranged with an adjustable spacing within the housing, thereby enabling adjustment of the diameter of a third beam channel 34 between the first N-pole electromagnet 311 and the first S-pole electromagnet 312.

[0059] The second N-pole electromagnet 321 and the second S-pole electromagnet 322 are arranged with an adjustable spacing inside the housing, thereby allowing adjustment of the diameter of another third beam channel 34 between the second N-pole electromagnet 321 and the second S-pole electromagnet 322.

[0060] The dual-beam deflection device 30 adopts an adjustable structure with a certain degree of self-adaptability, enabling it to adapt to different energies and types of beams.

[0061] Although embodiments of this application have been shown and described above, the scope of protection of this invention is not limited thereto. Any variations or substitutions that can be conceived without inventive effort should be covered within the scope of protection of this invention. Unless expressly stated otherwise, no element, action or instruction used herein should be construed as critical or necessary.
