Comments: Until approximately 21:30, almost every beam rf trip was accompanied by an HV failure in the BB, ostensibly due to beam spray as beam was restored. An extensive beam retune followed. Starting at 22:30, BB HV remained on through beam trips. BANU time almost completely due to time required to reset HV.
