Crew:
J. Roche (SL)
F. Itard (TO)
D. Flay
Highlights:
DAQ test going on up to 4am.
Production after that. We even took Compton data
It's freezing in the counting house !
Timeline:
- 00:00: starting with a controlled access in progress.
Here is a summary of what Alex did on the DAQ side.
- 03:00: Alex Camsonne is out of the hall and gives us the go ahead
for taking beam. The empty target is in the beam path. The magnet is
set for pnom=1.494 GeV, its angle is 31.819. HV are on on the LHRS
detectors and on the DVCS calorimeter. The beam is going through the
compton chicane. Theta calo=14.78 deg and at 1.1 m of the target.
- 3:15: harps look good (width 0.180 mm in all directions), put on
LH2 15 cm, DAQ setting is TrigDVCS, prescales at 0 but for ps5=1.
- 3:45 Compton rates look reasonnable, start taking Compton data.
- 4:15: 4 blocks of the DVCS calo are over counting
