| KEK Accelerator Test Facility (ATF) conducts beam instrumentation R&D for International Linear Collider (ILC) project. ATF includes 1.3 GeV normal conductive S-band Linac and Damping Ring (DR). There are 9 S-band pulsed klystrons at Linac, which supply High-Power RF to accelerate electron beam up to 1.3 GeV, and 1 CW klystron at DR. Linac and DR High-Power RF field stabilization will improve the ATF performance. As a first step, the RF field phase and amplitude stability was measured. This report demonstrates KEK ATF Linac and DR High-Power RF field phase and amplitude stability measurement results. Also, a solution to stabilize the RF field is discussed. |
