METHOD OF MANUFACTURING OUTER CONDUCTOR

摘要

Disclosed is a method of manufacturing an outer conductor, wherein an outer conductor of a high-frequency coupler is manufactured inexpensively, and without using so much material. The method of manufacturing an outer conductor is for manufacturing an outer conductor (13) of a high-frequency coupler of a superconducting acceleration cavity wherein the outer conductor (13) is provided with: a cylinder-shaped body section (15) that has one end-face thereof opened; a port section (17) formed at the side section of the body section (15) so as to penetrate therethrough; and a protrusion section (21) formed outside the other end-face of the body section (15). The method of manufacturing an outer conductor is provided with: a deep drawing process for deep drawing a metal plate, and forming the body section (15); a port-section forming process for processing a flange onto the formed body section (15), to form the port section (17); and a first machine-processing process for machine-processing the external shape of the body section (15), and tidying up the external shape.
