keyword=RICH HV Trips19:31 RICH HV tripped, cleared alarms and turned HV off and on, then RICH tripped off again. Paged Bodo.
19:45 Called RC (Guido), since Bodo has not called back, and he said he would look into it.
19:51 Asked for beam off until RICH is back up.
19:55 Pete Markowitz called and he suggested that I lower the HV from 2100 V to 2075 V.
20:02 Turned RICH HV on. Ramped up without problems.
20:04 Asked for beam back at 100 uA.
