lem without 1L12-6

6 days ago
Log Number: 4290857Logbook(s): Entry Makers: kpriceBody: 

to get 1L12 back, we have to lose cavity 6. With the linac @ 300 uA and 4 MeV in the lock we're looking at 60 trips/shift in the north. We can drop the linac current to 250 and put 3 in the lock for a slightly more survivable 52 trips/shift. As we haven't had more than 175 uA in the linac since February, we'll try that for now.

Raised 1L26 HV & Characterized Klystrons

6 days 1 hour ago
Log Number: 4290852Logbook(s): Entry Makers: bschaumlBody: 

I raised the voltage for 1L25 yesterday morning, so with the blessing of the on-call expert we decided to give 1L26 a go. Noted that HV for bay 3 is ~0.6 kV higher than the others. The CRFPPkc vs CRFPkc graph for cavity 1 wrapped around in an odd way (I've only seen examples with one step on 1L25 versus the three seen here) so I included extra screengrabs of the extrema.

1L12 dropped HV

Won't come back up into HV. Tried dropping down to idle - no luck. Went out there and saw the breaker was tripped. Calling RF on call.
