Abstract

The invention relates to a single mandril spoke type superconductive accelerating cavity and a manufacture method thereof. The accelerating cavity is characterized by comprising a cylindrical cavity barrel which is formed by punching and welding four arch plates, wherein a mandril hole is respectively formed on each of two opposite arch plates; a cleaning tube is respectively arranged on each of the other two opposite arch plates; one end of each cleaning tube positioned outside the cavity barrel is respectively connected with a flange; two ends of the cavity barrel are respectively provided with an end cover; the middle of the surface of each end cover is internally indented, and an end cover beam tube respectively penetrates through the middle of the surface of each end cover; the two end cover beam tubes are respectively connected with a flange; the mandril is arranged between the mandril holes in the cavity barrel; the mandril is a thin wall cavity, the middle section of the mandril is in a straight barrel shape, the two ends of the mandril are in symmetrical funnel shapes, and two funnel-shaped ports are correspondingly arranged in the two mandril holes; a center beam tube penetrates through the middle section of the mandril; and the center beam tube and the two end cover beam tubes are positioned in the same axis. In the accelerating cavity, a transverse electromagnetic wave mode is adopted for acceleration, and the requirements of high gradient, high efficiency, high acceptability, high stability and the like can be met. The accelerating cavity can be used for accelerating protons at full energy section.

Description

technical field [0001] The invention relates to a superconducting accelerating cavity and a manufacturing method thereof, in particular to a single mandrel spoke-type superconducting accelerating cavity (superconducting Spoke cavity) for accelerating high-current protons and a manufacturing method thereof. Background technique [0002] With the development of accelerator technology, accelerators will be more and more widely used in fields such as scientific research, medical treatment, environmental protection, energy, and national defense security. According to the needs of various application fields, various technical requirements are put forward for the accelerator. Driven by the research needs of accelerator-driven subcritical reactors (ADS), high-current proton linear acceleration technology has become a type of accelerator technology that is currently in need of rapid development. This is mainly because it has irreplaceable advantages in nuclear material utilization, ...
