Late Entry: Pass 2 H separation re-done

8 hours 36 minutes ago
Log Number: 4481398Logbook(s): Entry Makers: samariBody: 

Quickly set up pass 2 separation after it tripped during Hall C's BNR for a HMS dipole change. Unfortunately forgot to grab photos, but B and D were on the recirculating wire as expected and C was on the extracted wire. It looks like we don't have rels past the dumplettew, but to the dumplette we were flat.

Log Number: 4481376Logbook(s): Entry Makers: lfarrishBody: 

Phone call from MCC about pass 2 no rf and after visual inspection I notice the crowbar on the 27 kv ps was fired. I reset this fault by way of the local control panel located on the 27 kv power supply itself

1L07 phase slip investigation

11 hours 17 minutes ago
Log Number: 4481334Logbook(s): Entry Makers: samariBody: 

given the oddities with 1L07, when we saw the beam smear I first checked if using 1L07 gangphase alone could remedy the issue. I found the maximum at +5 degrees of 1L07 GP, but not a lot of energy gain. When I put it back and used NL gang phase, there was a very large energy change and total NL PSET went +3.3 degrees and the energy changed by a full MV/m. It might be an individual cavity in 1L07, but the entire zone does not seem to be the problem.
