Problems solved by technology

In the design of a normal temperature synchrocyclotron, the rotation speed of the rotating capacitor is very low, and at the same time, the design of the cavity structure is complicated, and the electrical contact structure between the components is relatively cumbersome.
Conventional synchrocyclotron spin capacitor rotor electrical contact methods exhibit significant limitations in the design of high speed spin capacitors

Abstract

The present invention discloses an electric contact structure of rotation of a capacitance rotor in synchrophasotron and a structure thereof. The structure comprises a capacitance vacuum chamber, a capacitance rotor rotationally arranged in the capacitance vacuum chamber and a rotation shaft fixedly connected with one end of the capacitance rotor and configured to drive the rotation of the capacitance rotor. The capacitance rotor comprises a disc portion arranged at the middle portion and a blade portion distributed towards the outer side along the disc portion, the rotation shaft is providedwith an electric connection rotary table having an interval with the disc portion, and an electric connection copper mesh is crimped between the disc portion and the electric connection rotary table;and a planar narrow gap configured to perform high-frequency earthing is arranged between one side, far away from the disc portion, of the electric connection rotary table and the side wall of the capacitance vacuum chamber. The effect of electric contact can be stably achieved in a high-speed rotation condition.

Description

technical field [0001] The invention relates to the field of synchrocyclotrons, and more specifically relates to an electrical contact structure of a rotating capacitor rotor in a synchrocyclotron. Background technique [0002] In order to adapt to the influence of the theory of relativity, the frequency of the cavity decreases gradually during the ion acceleration process of the synchrocyclotron. After the beam is extracted, the frequency of the cavity is quickly returned to the initial acceleration frequency, and the acceleration of the next beam continues. The variation of the cavity frequency of a synchrocyclotron is generally achieved through periodic rotating capacitors. In the design of a normal temperature synchrocyclotron, the rotation speed of the rotating capacitor is very low, and at the same time, the design of the cavity structure is complicated, and the electrical contact structure between the components is cumbersome. In the design of high-speed spinning ca...
