RF Sources of Super-Conducting Test Facility(STF) at KEK

After ITRP’s technical choice, KEK tried to seek contributions for the international linear collider and made a plan for the super-conducting test facility (STF) at KEK. STF comprised phase-I and phase-II; the former is a plan for two years from FY2005, and is aimed at the quick construction of a test facility to evaluate 4-35MV/m cavity structures and 4-45 MV/m cavity structures with a beam. Phase-II is the next plan of the test facility to extend two 16m cryomodules. In this paper, a general description of the STF is made, and the rf source plan is described.
