Description

Technical Field

[0001] This application relates to the technical field of corrective magnets, and more particularly to a corrective magnet for particles. Background Technology

[0002] In the field of particle accelerator technology, precise correction of particle beam paths is a key step in ensuring the accuracy of experimental data and therapeutic effects. As high-energy physics experiments continue to demand higher particle beam energy and precision, the performance of traditional correction magnets has gradually become inadequate to meet the requirements. Medical particle therapy devices also face similar challenges.

[0003] The existing publication number CN209561018U, entitled "A Trajectory Corrector for Charged Particle Beams," includes: a first corrective magnet, used to deflect the forward direction of the charged particle beam by a preset angle; a second corrective magnet, used to adjust the forward direction of the charged particle beam to be parallel to the forward direction before the deflection; a distance adjustment device, the second corrective magnet being connected to the first corrective magnet via the distance adjustment device; the distance adjustment device being used to adjust the distance between the first and second corrective magnets to a preset distance; and a control device, the control device being electrically connected to the first corrective magnet, the second corrective magnet, and the distance adjustment device respectively.

[0004] Regarding the aforementioned technologies, the inventors discovered that under long-term continuous operation conditions, the correction magnets lack modular assembly frames and heat dissipation components. During long-term use, the correction magnets lack a cooling system, resulting in low heat dissipation efficiency. The magnets are prone to overheating and performance degradation during long-term high-load operation. The non-modular structure limits the application scenarios of the magnets and makes it impossible to flexibly meet diverse needs. Utility Model Content

[0005] To overcome the shortcomings of existing magnets, such as the lack of modular assembly frames and heat dissipation components, the low heat dissipation efficiency of correction magnets without cooling systems during long-term use, and the performance degradation of magnets due to overheating during long-term high-load operation, and the limitation of magnets' application scenarios by non-modular structures, making it impossible to flexibly meet diverse needs, this application provides a correction magnet for particles.

[0006] The corrective magnet for particles provided in this application adopts the following technical solution:

[0007] A particle correction magnet includes a mold frame, connectors, magnets, and a cooling component. Connectors are provided on both the upper and lower sides of the mold frame, and the connectors are used to connect adjacent mold frames. The cooling component includes a cooling tube that is horizontally fixed to the mold frame, and both ends of the cooling tube are connected to and fixed with a diverter pipe. Two magnets are symmetrically arranged on both the upper and lower sides of the mold frame, and cooling grooves are formed on the adjacent vertical end faces of the two magnets. The cooling grooves on the two magnets are engaged with the cooling tube. A locking screw groove is vertically formed on the magnet. Locking bolts are vertically threaded through the upper and lower end faces of the mold frame, and the locking bolts are threaded into the locking screw grooves.

[0008] By adopting the above technical solution, two magnets are symmetrically arranged inside the mold frame during use. Cooling grooves are opened on the side of the two magnets near the cooling tube. The cooling grooves on the magnets are in abutting contact with the cooling tube. Then, the locking bolts are threaded through the mold frame and simultaneously assembled into the locking screw grooves on the top surface of the magnets, completing the fixed assembly of the magnets and the mold frame. The magnets are locked and fixed by the locking bolts, ensuring the stability of the assembly of the magnets and the mold frame. At the same time, the heat in the magnets is transferred to the outer wall of the cooling tube. The coolant flowing in the cooling tube contacts the outer wall to dissipate the heat in the magnets. Thus, the cooling component serves as the cooling system for the correcting magnets, ensuring improved heat dissipation efficiency.

[0009] Optionally, a circulating pump is connected and fixed to the diversion pipe, and an assembly flange ring is connected and fixed to the end of the diversion pipe, and the assembly flange ring is connected and fixed to the external liquid supply pipeline.

[0010] By adopting the above technical solution, during startup, the assembly flange ring at the end of the split pipe is connected and fixed to the external liquid supply pipe. The circulation pump on the split pipe is started to drive the coolant into the cooling tube. The flowing coolant contacts the outer wall to dissipate heat from the magnet.

[0011] Optionally, sliding frames are horizontally fixed on both the upper and lower sides of the vertical end faces of the mold frame, and multiple positioning screw holes are opened horizontally and vertically through the top surface of the sliding frames.

[0012] By adopting the above technical solution, sliding frames are horizontally fixed on both the upper and lower sides of the vertical end faces of the mold frame. The multiple positioning screw holes on the sliding frames facilitate the later adjustment and positioning control of the distance between the two mold frames.

[0013] Optionally, a pull plate is horizontally slidably inserted into the slide frame, and a slider is fixed at one end of the pull plate, and the slider is horizontally slidably assembled in the slide frame.

[0014] By adopting the above technical solution, the pull plate is pulled to slide in the slide frame according to the distance between the two mold frames, and the slider is pulled to move laterally in the slide frame to adjust the positioning control of the distance between the two mold frames.

[0015] Optionally, the slider has a vertical thread that passes through a locking screw hole.

[0016] By adopting the above technical solution, the locking screw hole provided on the slider facilitates the control of the extension length of the pull plate in the slider frame.

[0017] Optionally, a limit bolt is assembled through the vertical thread in the positioning screw hole of the slide frame, and the thread of the limit bolt is assembled in the locking screw hole of the slide block.

[0018] By adopting the above technical solution, when the sliding frame positioning pull plate is pulled, the locking screw hole of the slider is assembled with the limit bolt thread, and the length position of the sliding frame positioning pull plate is completed, thereby adjusting and controlling the distance between the two mold frames.

[0019] Optionally, the connector includes a slot plate with a slot and a threaded hole through the slot. The slot plate engages with the end of the pull plate and is fixedly assembled with the end of the pull plate by connecting bolts.

[0020] By adopting the above technical solution, the slot on the slot plate is engaged with the end of the pull plate, and then the slot plate is fixedly assembled with the end of the pull plate by connecting bolts, thereby ensuring the stability of the spacing between the two mold frames supported by the slot plate in the later stage.

[0021] Optionally, both sides of the slot plate are fixed with screw hole strips, and the ends of the screw hole strips are horizontally threaded with fixing bolts.

[0022] By adopting the above technical solution, the ends of the screw holes on both sides of the slot plate are equipped with fixing bolts with horizontal threads to lock and fix the slot plate, thereby improving the support stability of the slot plate in the later stage of the snap-fit.

[0023] In summary, this application includes at least one of the following beneficial technical effects: During use, two magnets are symmetrically arranged inside the mold frame. Cooling grooves are formed on the side of the two magnets closest to the cooling tube. The cooling grooves on the magnets are in abutting contact with the cooling tube. Then, locking bolts are threaded through the mold frame and simultaneously threaded into the locking screw grooves on the top surface of the magnets, completing the fixed assembly of the magnets and the mold frame. The magnets are locked in place by the locking bolts, ensuring the stability of the assembly between the magnets and the mold frame. Simultaneously, the heat in the magnets is transferred to the outer wall of the cooling tube. The coolant flowing in the cooling tube contacts the outer wall, dissipating the heat from the magnets. Thus, the cooling component serves as the cooling system for the correcting magnets, ensuring improved heat dissipation efficiency. Attached Figure Description

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a corrective magnet for particles. (See also...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A particle correction magnet includes a mold frame 1, a connector 2, a magnet 3, and a cooling component 4. The mold frame 1 has connectors 2 on both its upper and lower sides, and the connectors 2 are used to connect adjacent mold frames 1. The cooling component 4 includes a cooling tube 41, which is horizontally fixed to the mold frame 1. Both ends of the cooling tube 41 are connected and fixed with a diverter pipe 42. Two magnets 3 are symmetrically arranged on both the upper and lower sides of the mold frame 1. Cooling grooves 32 are opened on the adjacent vertical end faces of the two magnets 3, and the cooling grooves 32 on the two magnets 3 are engaged and snapped onto the cooling tube 41. A locking screw groove 31 is vertically opened on the magnet 3. A locking bolt 11 is vertically threaded through and assembled on both the upper and lower end faces of the mold frame 1, and the locking bolt 11 is threaded into the locking screw groove 31.

[0032] By adopting the above technical solution, two magnets 3 are symmetrically arranged inside the mold frame 1 during use. Cooling grooves 32 are opened on the side of the two magnets 3 near the cooling tube 41. The cooling grooves 32 on the magnets 3 are in abutting contact with the cooling tube 41. Then, the locking bolts 11 are threaded through the mold frame 1 and simultaneously threaded onto the locking screw grooves 31 on the top surface of the magnets 3, thus completing the fixed assembly of the magnets 3 and the mold frame 1. The magnets 3 are locked and fixed by the locking bolts 11, ensuring the stability of the assembly of the magnets 3 and the mold frame 1. At the same time, the heat in the magnets 3 is transferred to the outer wall of the cooling tube 41. The coolant flowing in the cooling tube 41 contacts the outer wall to dissipate the heat in the magnets 3. Thus, the cooling component 4 serves as the cooling system for the correcting magnets, ensuring improved heat dissipation efficiency.

[0033] Reference Figure 3 and Figure 4 A circulation pump 43 is fixedly connected to the distribution pipe 42, and an assembly flange ring 45 is fixedly connected to the end of the distribution pipe 42, and the assembly flange ring 45 is fixedly connected to the external liquid supply pipe. During startup, the assembly flange ring 45 at the end of the distribution pipe 42 is fixedly connected to the external liquid supply pipe, and the circulation pump 43 on the distribution pipe 42 is started to drive the coolant into the cooling tube 41. The flowing coolant contacts the outer wall to dissipate heat from the magnet 3.

[0034] Reference Figure 4 Both sides of the vertical end face of the mold frame 1 are horizontally fixed with sliding frames 12, and multiple positioning screw holes 121 are horizontally and vertically through the top surface of the sliding frames 12. The multiple positioning screw holes 121 on the sliding frames 12 facilitate subsequent adjustment and positioning control of the distance between the two mold frames 1. A pull plate 13 is horizontally slidably inserted into the sliding frame 12, and a slider 14 is fixed to one end of the pull plate 13. The slider 14 is horizontally slidably assembled in the sliding frame 12. Pulling the pull plate 13 to slide within the sliding frame 12 according to the distance between the two mold frames 1 causes the slider 14 to move laterally within the sliding frame 12, thus adjusting and controlling the distance between the two mold frames 1. A locking screw hole 141 is vertically threaded through the slider 14. The locking screw hole 141 on the slider 14 facilitates control of the extension length of the pull plate 13 in the sliding frame 12. A vertical thread passes through the positioning screw hole 121 of the slide frame 12 to assemble a limit bolt 122, and the limit bolt 122 is threaded into the locking screw hole 141 of the slider 14. When the slide frame 12 positions the pull plate 13, the threaded assembly of the limit bolt 122 into the locking screw hole 141 of the slider 14 completes the extension length position of the slide frame 12 positioning pull plate 13, thereby adjusting and controlling the distance between the two mold frames 1.

[0035] Reference Figure 5The connecting component 2 includes a slotted plate 21 with a slot on it. A vertically threaded screw hole is formed through the slot. The slotted plate 21 engages with the end of the pull plate 13 and is fixedly assembled to the end of the pull plate 13 by connecting bolts 131. The engagement of the slotted plate 21 with the end of the pull plate 13, and then the fixing of the slotted plate 21 to the end of the pull plate 13 by connecting bolts 131, ensures the stability of the spacing between the two mold frames 1 in the later stages of support. Screw-hole strips 22 are fixed on both sides of the slotted plate 21, and fixing bolts 23 are horizontally threaded at the ends of the screw-hole strips 22. The fixing bolts 23 on the horizontally threaded ends of the screw-hole strips 22 on both sides of the slotted plate 21 lock and fix the slotted plate 21, improving the later-stage support stability of the slotted plate 21.

[0036] The implementation principle of a particle correction magnet in this application embodiment is as follows: During use, two magnets 3 are symmetrically arranged inside the mold frame 1. Cooling grooves 32 are formed on the side of the two magnets 3 closest to the cooling tube 41. The cooling grooves 32 on the magnets 3 are in abutting contact with the cooling tube 41. Then, locking bolts 11 are threaded through the mold frame 1 and simultaneously threaded into the locking screw grooves 31 on the top surface of the magnets 3, completing the fixed assembly of the magnets 3 and the mold frame 1. The magnets 3 are locked and fixed by the locking bolts 11, ensuring the stability of the assembly between the magnets 3 and the mold frame 1. Simultaneously, the heat in the magnets 3 is transferred to the outer wall of the cooling tube 41. During startup, the assembly flange ring 45 at the end of the distribution pipe 42 is connected and fixed to the external liquid supply pipe, and the circulation pump 4 on the distribution pipe 42 is started. 3. The coolant flowing into the cooling tube 41 contacts the outer wall to dissipate heat from the magnet 3. The cooling component 4, as the cooling system for the correcting magnet, ensures improved heat dissipation efficiency. The pull plate 13 is pulled to slide in the slide frame 12 according to the distance between the two mold frames 1. When the slide frame 12 positions the pull plate 13, the limit bolt 122 is threaded onto the locking screw hole 141 of the slider 14 to complete the length position of the extended pull plate 13, thereby adjusting and controlling the distance between the two mold frames 1. The slot on the slot plate 21 is engaged with the end of the pull plate 13. Then, the slot plate 21 is fixedly assembled with the end of the pull plate 13 by the connecting bolt 131.
