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 (3) is formed by forming a recessed iris portion (3b) around the central part of a cylindrical pipe made of a superconducting material, a cup-shaped half cell (2) 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 (3) are coupled by welding, and the each half cell (2) is welded to the opposite ends of the plurality of dumbbell cell (3), thus producing a superconducting acceleration cavity (1).
