Shift workers:
Chao Gu(SL), Navaphon Muangma(TO), Patricia Solvignon-Slifer(3rd)
08:00 Shift starts. Pengjia is doing slow raster calibration.
10:30 Pengjia finished his beam line calibration. We start to center
beam.
11:30 Right septa tripped at 900A. Jack came here and reset it. The
new limit for right septa is 850A. We are not able to do optics at this
setting.
12:30 Right septa tripped again at 840A. Jack reset it again and set
the new limit to be 800A. Meanwhile MCC is doing some trouble shooting
work on C100 cavities.
13:15 We move LHRS to 2.2510GeV (Septa 725.4A) RHRS to 1.7348GeV
(Septa 724.6A) for safe.
13:30 No beam in the Hall. MCC is checking some IOC problem.
15:30 Escorted access for multiple trouble shooting work. Heidi is
working on left arm's dipole valve. Jack is trying to find out the reason
of the septa trip.
16:00 Shift ends. We still do not have beam in the hall. Heidi and
Jack are still in the hall to do their work.
