Milestones achieved during RF processing - 10th of September 2009

While continuing RF processing of the RF cavity, the level of RF input power is gradually increasing. For instance, on the 10th of September we could ramp up very fast up to 3.9-MW input power and 3.0-MeV electron energy at 50 Hz without experiencing any breakdown.

By the end of the day the level of 7.1-MW input power and 3.8-MeV electron energy has been reached in case of a 1.0-us short pulse and 40-Hz repetition frequency. The measured peak dark current was 0.17 mA and the charge per pulse was 0.079 nC.
