Description

Technical Field

[0001] The present invention relates to the technical field of cyclotron accelerators, and in particular to a connection component for connecting a D-box, a high-frequency device and a cyclotron accelerator system. Background Art

[0002] The resonant cavity of the cyclotron is used to generate a high-frequency alternating electric field to accelerate charged particles. In this process, when the high-frequency current passes through the wall of the resonant cavity, power loss will occur due to the resistance of the conductor. According to Joule's law, Q = I 2 Rt (where Q is heat, I is current, R is resistance, and t is time). The high-frequency current generates heat on the resistance of the resonant cavity wall. At the same time, the high-frequency cavity is in a vacuum environment, and the heat dissipation effect is poor, which often leads to excessively high temperatures in local areas of the resonant cavity wall, causing thermal deformation of the high-frequency cavity, thereby reducing the working stability of the cyclotron. The resonant cavity is composed of an outer conductor and an inner conductor. The inner conductor is generally composed of two D boxes arranged at 180°. Due to the small conductive cross-sectional area, the head of the D box and the connecting bridge generate severe heat. Among them, the D box is an important component of the resonant cavity. Because it is fixed by a high-frequency rod with a smaller diameter, and the upper and lower D plates have the structural characteristics of being fixed at both ends and suspended in the middle, studying the heat dissipation of the resonant cavity has always been a research hotspot for technicians in this field.

[0003] The two common technical solutions for D boxes are double high-frequency rod D boxes (there are high-frequency rods on both the top and bottom of the D box) and single high-frequency rod D boxes (there is only a high-frequency rod on the bottom of the D box). The two D boxes are connected by bridges and connecting components. High-frequency alternating current will continuously pass through the bridges and connecting components, causing the bridges and connecting components to heat up severely, causing the bridges and connecting components to deform thermally, and affecting the normal operation of the two D boxes.

[0004] In the relevant technical solution, the structure of the bridge is a metal rod, which is fixed to the two D-box heads by screws, mainly to make the two D-boxes electrically connected. In the resonant cavity of the cyclotron, the installation space of the D-box head is very small, resulting in the metal rod being not firmly fixed. In addition, since the D-box head is small in size and connected to the D-plate by screws, the D-plate water cooling channel is difficult to arrange near the D-box head, resulting in severe heating of the bridge and the D-box head, causing thermal deformation of the bridge and the D-box head.

[0005] In the prior art, how to solve the serious heating problem of the head of the dual high-frequency rod D box and the connection structure between the dual high-frequency rod D boxes is a technical problem that needs to be solved urgently by technical personnel in this field.

Preferably, the first heat exchange tube 410 can be buried in the rod wall of the lower high frequency rod of the first D box 200. In addition, the first heat exchange tube 410 is coiled in the lower D plate of the first D box 200, which can increase the contact area between the first heat exchange tube 410 and the lower D plate of the first D box 200, thereby improving the heat exchange efficiency of the first heat exchange tube 410 to the lower D plate of the first D box 200.

[0080] In addition, the second heat exchange tube 420 extends from the lower high-frequency rod of the first D box 200, bypassing the suspended space between the upper D plate and the lower D plate.
