US 10,383,204 B2 · Superconducting accelerator

Abstract

A superconducting accelerator includes an acceleration cavity, and a refrigerant tank at an outer circumference of the acceleration cavity. The gap between the refrigerant tank and the acceleration cavity is filled with a refrigerant for cooling the acceleration cavity. A pair of pressing members is provided to an outer circumference of the refrigerant tank to be positioned at both side ends of the acceleration cavity in a direction of a beam axis of the charged particle beam or at both ends of the acceleration cavity in a direction perpendicular to the beam axis. A wire is continuously wound around the outer circumference of the refrigerant tank and configured to generate a tensile force in a direction in which the pressing members are brought come into close each other. A tension adjustor is configured to adjust the tensile force generated by the wire.
