PURPOSE:To provide a superconductive acceleration tube which can be manufactured in a short manufacturing time, with a simple jig, at a low cost, and with an easy weld work, and provide manufacturing thereof for the acceleration tube having equivalent or exceeding characteristics to those obtained by electron beam weld in manufacturing the superconductive acceleration tube. CONSTITUTION:A superconductive acceleration tube 10 is composed of a plural component parts 11, 12, 13 comprising superconductive material welded with each other at peripheral parts. The superconductive acceleration tube 10 is welded by a laser beam at each peripheral part. The component parts 11, 12, 13 having the peripheral parts to be put to each other and comprising the superconductive material are laser welded by a laser beam radiated to the peripheral parts. |
