Abstract
A superconducting accelerating cavity production method with which a high-quality superconducting accelerating cavity can be produced with a compact device configuration and at low cost. The method of producing a superconducting accelerating cavity () includes arranging, in an axial direction (L), a plurality of half-cells () having openings at both ends in the axial direction and joining the openings to one another by welding. The half-cells () are joined by welding with a laser beam from the inside of the superconducting accelerating cavity () in which a vacuum atmosphere is created.
