Single-mandril spoke type superconduction accelerating cavity and manufacture method thereof

Abstract

The invention relates to a single-mandril spoke type superconduction accelerating cavity and a manufacture method thereof, wherein an optimal beta range is 0.1-0.1. The single-mandril spoke type superconduction accelerating cavity comprises a cavity body. The cavity body is formed by two semi-cavity bodies with the same shape in a welding mode. The outline of the cavity body is in an ellipsoid shape. A pair of beam tube holes is symmetrically formed in the center of the cavity body. A beam tuber is welded in each of the two beam tube holes. A flange is welded on the outer side of each of the two beam tubes. A pair of mandril holes is symmetrically formed in the cavity body and is perpendicular to the direction of the connecting line of the two beam tubes. A pair of cleaning holes is symmetrically formed in the cavity body and is 90 degrees away from the two mandril holes. A mandril which is formed by two half thin-wall cavities in a welding mode is welded in the two mandril holes. The middle section of the mandril is in straight barrel shape, and two ends of the mandril are in a symmetrical hopper shape. The two hopper-shaped end openings are respectively welded on the corresponding mandril holes. A center beam tube penetrates through and is welded on the middle section of the mandril. The center beam tube is located on the same axis with the beam tubes at the two ends. A cleaning tube is welded in each of the two cleaning holes. A flange is welded on the outer side of each of the two cleaning tubes, and the flanges are connected with an external device. The single-mandril spoke type superconduction accelerating cavity can be well applied to an injector of an accelerator transmutation system.

Description

technical field [0001] The present invention relates to a strong current proton acceleration chamber, in particular to a single mandrel spoke type superconducting acceleration chamber which can suppress the secondary electron multiplication effect and its Manufacturing method. Background technique [0002] In recent years, the use of nuclear energy has developed rapidly in our country, and the safety of nuclear energy use and nuclear waste disposal have become the main issues that limit the development of nuclear energy in the future. As one of the solutions to the nuclear energy utilization problem, the accelerator-driven transmutation system is mainly composed of a high-current proton linear accelerator and a high-throughput target. The single-mandrel spoke-type superconducting cavity is one of the important components of the high-current proton linear accelerator (such as Figure 5 ~ Figure 7 shown), especially for the acceleration of the middle and low energy segments. ...
