Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figure 1 and Figure 2 As shown, the voltage-type noise signal suppression device 100 of a particle accelerator according to an embodiment of the present invention includes a first conductive terminal 1 , a second conductive terminal 2 and a suppression component 3 .

[0021] The first conductive terminal 1 is suitable for being electrically connected to the vacuum tube 101 .

[0022] The second conductive terminal 2 is suitable for being electrically connected to the magnet 102 .

[0023] The suppression assembly 3 includes a box body 30, a suppressor 33, a first terminal 31 and a second terminal 32. The suppressor 33 is arranged in the box body 30. The first terminal 31, the suppressor 33 and the second terminal 32 are arranged in sequence along a first direction. The first terminal 31 is used to electrically connect the first conductive terminal 1 and the suppressor 33. The second terminal 32 is used to electrically connect the second conductive terminal 2 and the suppressor 33.

[0024] In order to make the technical solution of the present application easier to understand, the technical solution of the present application is further described below by taking the first direction being consistent with the left-right direction as an example, wherein the left-right direction is as follows: Figure 1 and Figure 2 shown.

[0025] The particle accelerator includes a vacuum tube 101, a magnet 102, a voltage-type beam detector 103, and a bracket 104. The magnet 102 and the voltage-type beam detector 103 are both arranged on the outer peripheral side of the vacuum tube 101, wherein the magnet 102 is arranged on the right side of the voltage-type beam detector 103. The vacuum tube 101, the magnet 102, and the voltage-type beam detector 103 are all arranged on the bracket 104.

[0026] The suppressor 33 is disposed in the box body 30, and the first terminal 31, the suppressor 33, and the second terminal 32 are sequentially arranged along the left-right direction, the first terminal 31 is used to realize the electrical connection between the first conductive terminal 1 and the suppressor 33, and the second terminal 32 is used to realize the electrical connection between the second conductive terminal 2 and the suppressor 33. That is, the first conductive terminal 1, the first terminal 31, the suppressor 33, the second terminal 32, and the second conductive terminal 2 are sequentially connected in series.

[0027] The voltage-type noise signal suppression device 100 of the particle accelerator of the embodiment of the present invention connects the suppression component 3 to the vacuum tube 101, so that the suppression component 3 can effectively absorb or suppress the induced voltage generated when the magnet 102 power supply, high-frequency power source, high-voltage pulse source, etc. act on the wall of the vacuum tube 101, and guide the induced voltage back to the magnet 102, thereby reducing the interference to the voltage-type beam detector 103 and improving its detection accuracy and reliability.

[0028] Optionally, both the first wiring terminal 31 and the second wiring terminal 32 are press-type wiring terminals, and both ends of the first wiring terminal 31 and the second wiring terminal 32 are provided with a pressing portion and a wire pressing hole, and the wire pressing hole of the first wiring terminal 31 can be opened or closed by pressing the pressing portion, and similarly, the wire pressing hole of the second wiring terminal 32 can be opened or closed by pressing the pressing portion. In this way, the wire can be easily inserted or removed without using tools, thereby facilitating connection.

[0029] In some embodiments, the suppression component 3 is disposed adjacent to the first conductive terminal 1 relative to the second conductive terminal 2 .

[0030] For example, Figure 1 As shown, the length of the wire between the suppression component 3 and the first conductive terminal 1 is shorter than the length of the wire between the suppression component 3 and the second conductive terminal 2 . In other words, the suppression component 3 is disposed closer to the vacuum tube 101 relative to the magnet 102 .

[0031] The voltage-type noise signal suppression device 100 for a particle accelerator according to an embodiment of the present invention can minimize the distance that the induced voltage is transmitted from the magnet 102 to the wall of the vacuum tube 101 by placing the suppression component 3 closer to the vacuum tube 101, thereby effectively preventing or weakening the propagation of these induced voltages. In this way, the induced voltage is significantly attenuated before reaching the voltage-type beam detector 103, thereby ensuring the stability of the reference potential of the voltage-type beam detector 103 and improving the accuracy and reliability of the detection results.

[0032] In some embodiments, the suppressor 33 includes a capacitor 331, the box body 30 includes a bottom plate, the capacitor 331 is fixed to the bottom plate by a fastener 34, the fastener 34 includes a fixing portion 342 and two connecting ends 341 arranged opposite to each other in a second direction, the second direction is orthogonal to the first direction, the fixing portion 342 is arranged between the two connecting ends 341, the two connecting ends 341 are both fixedly connected to the bottom plate, and the fixing portion 342 is in contact with the surface of the capacitor 331 to fix the capacitor 331 to the bottom plate.

[0033] In order to make the technical solution of the present application easier to understand, the technical solution of the present application is further described below by taking the second direction being consistent with the front-to-back direction as an example, wherein the front-to-back direction is Figure 1 shown.

[0034] A capacitor 331 or multiple capacitors 331 are provided in the suppressor 33 , and the value of the capacitor 331 is designed according to actual working conditions.

[0035] The fastener 34 extends in the front-to-back direction, and the front and rear ends of the fastener 34 are both connecting ends 341, and the connecting ends 341 are connected to the bottom plate by bolts or clamping. The shape of the fixing portion 342 is adapted to the surface of the capacitor 331, so that the capacitor 331 can be stably fixed in the box body 30, ensuring that it will not be displaced or loosened during operation, thereby ensuring the reliability and effectiveness of the suppression component 3. This layout not only simplifies the installation process, but also improves the stability of the voltage-type noise signal suppression device 100 for the particle accelerator.

[0036] In some embodiments, a first groove and a second groove are provided on the bottom plate. The first groove is used to fix the first wiring terminal 31 , and the second groove is used to fix the second wiring terminal 32 .

[0037] For example, Figure 1 As shown, the first wiring terminal 31 is bonded or clamped in the first groove, and the second wiring terminal 32 is bonded or clamped in the second groove. Therefore, the voltage-type noise signal suppression device 100 for a particle accelerator according to the embodiment of the present invention can prevent the wiring terminals from loosening or shifting during use by fixing the first wiring terminal 31 and the second wiring terminal 32 in the corresponding first groove and the second groove, thereby ensuring the long-term stability of the electrical connection and the reliability of the signal transmission, and further ensuring the stability of the voltage-type noise signal suppression device 100 for a particle accelerator.

[0038] In some embodiments, the voltage-type noise signal suppression device 100 of the particle accelerator also includes a conductive sheet 35. In the first direction, the conductive sheet 35 is arranged on the side of the first terminal 31 away from the suppressor 33. The conductive sheet 35 is fixedly connected to the side wall of the box body 30. The first terminal 31 is electrically connected to the first conductive terminal 1 through the conductive sheet 35.

[0039] For example, Figure 1 As shown, the conductive sheet 35 is arranged on the side of the first terminal 31 away from the suppressor 33, that is, the conductive sheet 35 is arranged on the left side of the first terminal 31, and the conductive sheet 35 is bonded to the left side wall of the box body 30 or the conductive sheet 35 is connected to the left side wall of the box body 30 by snapping.

[0040] The first terminal 31 is electrically connected to the first conductive terminal 1 through the conductive sheet 35. A wire hole is provided on the side wall of the box body 30 so that the first terminal 31 is connected to the conductive sheet 35 through a wire, or a recess is provided on the side wall of the box body 30, and the conductive sheet 35 is fixed in the recess as a part of the side wall.

[0041] In some embodiments, the voltage-type noise signal suppression device 100 for a particle accelerator further includes a conductive bellows 4 , one end of which is electrically connected to the conductive sheet 35 , and the other end of which is electrically connected to the first conductive terminal 1 .

[0042] For example, Figure 1 As shown, the conductive sheet 35 is circular and fits with the conductive bellows 4, the left end of the conductive bellows 4 is connected to the first conductive terminal 1 by clamping or welding, and the right end of the conductive bellows 4 is sleeved on the conductive sheet 35 or the right end of the conductive bellows 4 is welded to the conductive sheet 35. The first conductive terminal 1, the conductive bellows 4, the conductive sheet 35, the first terminal 31 and the suppressor 33 are connected in series in sequence.

[0043] The voltage-type noise signal suppression device 100 of the particle accelerator of the embodiment of the present invention utilizes the conductive bellows 4. On the one hand, since the conductive bellows 4 has a certain flexibility, it can be bent at a certain angle to adapt to the installation position of the first conductive terminal 1, thereby providing flexibility and convenience in installation. On the other hand, the conductive bellows 4 also has a certain rigidity. Compared with ordinary wire connections, it can ensure that the suppression component 3 can be stably maintained near the vacuum tube 101 after installation, and will not shake due to external vibrations or other factors, thereby significantly improving the stability and reliability of the suppression component 3 in suppressing induced voltage. In addition, the conductive bellows 4 is also better than ordinary wires in the ability to transmit induced voltage, and can more effectively conduct and process induced voltage, further enhancing the effect of the voltage-type noise signal suppression device 100 of the particle accelerator in suppressing induced voltage.

[0044] Optionally, an outer surface of the conductive bellows 4 is provided with an insulating layer.

[0045] In some embodiments, the first conductive terminal 1 includes a first connecting portion 12 and a first fitting portion 11 connected to each other, the first connecting portion 12 is electrically connected to the suppression component 3, the first fitting portion 11 is suitable for being electrically connected to the vacuum tube 101, and the diameter of the first fitting portion 11 is greater than the diameter of the first connecting portion 12.

[0046] For example, Figure 1 As shown, the first connecting portion 12 and the first fitting portion 11 are both cylindrical, the first connecting portion 12 is arranged on the right side of the first fitting portion 11, and the first fitting portion 11 is electrically connected to the tube wall of the vacuum tube 101.

[0047] The first connection portion 12 is connected to the conductive bellows 4 . For example, the conductive bellows 4 is sleeved on the outer circumference of the first connection portion 12 .

[0048] The first fitting portion 11 has a larger diameter, so that the first fitting portion 11 can better fit the wall of the vacuum tube 101, thereby ensuring the tightness of the electrical connection.

[0049] In other embodiments, the first fitting portion 11 is a frustum or a cuboid.

[0050] In some embodiments, the second conductive terminal 2 includes a second connecting portion 22 and a second fitting portion 21 connected to each other, the second connecting portion 22 is electrically connected to the suppression component 3, the second fitting portion 21 is suitable for being electrically connected to the magnet 102, and the diameter of the second fitting portion 21 is greater than the diameter of the second connecting portion 22.

[0051] The second connecting portion 22 and the second fitting portion 21 are both cylindrical, and the second connecting portion 22 is arranged on the left side of the second fitting portion 21, and the second fitting portion 21 is electrically connected to the magnet 102. The second connecting portion 22 is electrically connected to the first conductive terminal 1. The second fitting portion 21 has a larger diameter, so that the second fitting portion 21 can better fit the magnet 102, ensuring the tightness of the electrical connection.

[0052] In other embodiments, the second fitting portion 21 is a frustum or a cuboid.

[0053] In some embodiments, the first conductive terminal 1 and the second conductive terminal 2 both include a bonding surface, on which conductive glue is provided, the first conductive terminal 1 is electrically connected to the vacuum tube 101 through the conductive glue, and the second conductive terminal 2 is electrically connected to the magnet 102 through the conductive glue.

[0054] For example, Figure 1 As shown, the use of conductive adhesive can provide good conductivity and bonding performance, and maintain good contact even in harsh environments such as high temperature or vibration.

[0055] In the voltage-type noise signal suppression device 100 of the particle accelerator of the embodiment of the present invention, the first conductive terminal 1 and the second conductive terminal 2 can be firmly fixed at their respective connection points in this way, avoiding looseness or poor contact, thereby improving the working stability of the entire suppression component 3.

[0056] In some embodiments, the box body 30 includes a cover plate 301 , and the cover plate 301 is rotatably disposed on the box body 30 .

[0057] For example, Figure 1 As shown, the front end of the cover plate 301 is hinged to the box body 30 so that the cover plate 301 can rotate relative to the box body 30, and the rear end of the cover plate 301 is connected to the box body 30 by a buckle so as to facilitate opening or closing the cover plate 301, thereby ensuring the stability and sealing of the cover plate 301. This detachable design not only improves the flexibility and maintainability of the device, but also simplifies the production and assembly process, providing great convenience for the daily use and maintenance of the voltage-type noise signal suppression device 100 for particle accelerators.
