Just to keep people informed:
I'm afraid it seems today's attempt to work on the beam was for naught (the attempt was to go "off-crest" in the injector, rather than the South Linac):
From OPS Elog:
The changes that were worked on today were all backed out. We were unable to get high current back to Hall C with out 1L02 BLM trips. PD, Optics, and Director of Operations agreed to the back out. The halls were also notified. We rolled back to all save #12866. We also did an all save before backing out (# 12869). (see: OPS Elog 1661370)
However, Jay points out were are now closer to Crest in the South Linac gang phase (see OPS Elog 1661368)
and also that we might expect a lower trip rate, see: OPS Elog 1661373.
