PROBLEM TO BE SOLVED: To obtain a superconducting high frequency accelerating cavity that is stable in quality, wherein complicated works in the aspect of working environment, waste solution treatment and work management or the like are simplified without requiring a large cost. SOLUTION: In a manufacturing method of a superconducting high frequency accelerating cavity which is constituted of the cavity main body composed of a superconducting material and of flanges mounted on both ends of the cavity main body, in which a high-frequency electric power is inputted into the cavity of the cavity main body to generate an electric field, and in which charged particles are accelerated by the electric field, plural cells having openings in both ends in the shaft direction are arranged in the shaft direction and make mutual openings come into contact with each other, and the one cavity main body is formed by the integration as the contact parts are made to be weld-joined, and next the inner face of the cavity main body is roughly abraded after the cavity main body is formed, and afterwards, a surface treatment is carried out as the post-finishing abrasion wherein a mirror face is finished by mechanical abrasion by means of an abrasive or an abrasive solution, in which a ceramic type abrasive is contained. |
