Abstract

Pohang Accelerator Laboratory, POSTECH have studied SRF cavity and constructed SRF test laboratory from January 2006. The first activity for SRF research was to develop SRF 3^rd harmonic cavity for PLS, which cavity was done in 2006 and the cryostat are under design. The fabrication of ICHIRO cavity, which is ILC ACD cavity, is PAL´s second activity related to SRF. Deep drawing, trimming and welding by electron beam for a 9-cell ICHIRO cavity were done in PAL. The polishing processes of RF surface including electro-polishing were done in KEK with collaboration. This will be tested with real beam in STF-1 of KEK in second half period of 2007. This paper reports fabrication of ICHIRO nine-cell cavities in PAL.
