Abstract
A method for producing a superconducting acceleration cavity having a stabilized quality, by which production cost is reduced by reducing the number of welding points. A dumbbell-shaped dumbbell cell () is formed by forming a recessed iris portion () around the central part of a cylindrical pipe made of a superconducting material, a cup-shaped half cell () is formed by enlarging one opening and reducing the other opening of the cylindrical pipe made of a superconducting material, a plurality of dumbbell cells () are coupled by welding, and the each half cell () is welded to the opposite ends of the plurality of dumbbell cell (), thus producing a superconducting acceleration cavity ().
