MANUFACTURE OF SUPERCONDUCTING HIGH-FREQUENCY CAVITY AND SUPERCONDUCTING HIGH-FREQUENCY CAVITY MANUFACTURED THEREBY

摘要

PROBLEM TO BE SOLVED: To facilitate manufacturing, to reduce the manufacturing cost, to improve performance and to economize. ;SOLUTION: This cavity is manufactured as follows. A cylinder 1 made of superconducting material, an inner cylinder 3 and an outer cylinder 2 made of good heat conductive material are prepared. By inserting the cylinder 1 into a hollow part of the outer cylinder 2 and by inserting the inner cylinder 3 into a hollow part of the cylinder 1, an assembly is obtained. The assembly is integrally joined by use of at least a hot isotropic pressure joining method, while drawn to form an integrated cylinder. The integrated cylinder is set to a mold and formed into a shape along the mold shape by bulging. Then, the inner cylinder 3 is removed.;COPYRIGHT: (C)2000,JPO
