KEKにおけるILCのための超伝導９セル空洞製造の研究

STUDY ON FABRICATION OF SUPERCONDUCTING RF 9-CELL CAVITY FOR ILC AT KEK

We constructed a new facility for the fabrication of superconducting RF cavity at KEK from 2009 to 2011. In the facility, we have installed a deep-drawing machine, a half-cell trimming machine, an Electron-Beam Welding (EBW) machine, and a chemical etching room in one place. We started the study on the fabrication of 9-cell cavity for International Linear Collier (ILC) from 2009 using this facility. The study is focusing on the cost reduction with keeping high performance of cavity, and the goal is the establishment of mass-production procedure for ILC. This article reports the current status of the studies in this facility.
