1:17 Finished Q3_j40 production running. Switched the target to optics.
1:25 Did the pointing run (run # 3158).
1:40 Changed the right arm settings. Momentum is now at 1.805 GeV/c and the angle is 52.556 degrees. Mark did the harp scan.
1:50 Starting a Q3_j50 pointing run failed - communication lost with ROC4.
Rebooted fastbus crates several times - didn't help.
2:05 Requested access to the hall.
2:30 During the access it turned out that fastbus crate for ROC4 was not operational.
Bob Michaels created new DAQ configuration: NOROC4 (same as COINC but
with no ROC4 read in - so there is no FPP). Runs fine (run 3160).
3:00 Started optics run again (run 3161) - DAQ OK.
3:34 Q3_j50 production running begins (run # 3163).
4:26 MCC took the beam away for some orbit adjustments.
5:30 Beam is back but very unstable.
5:45 No beam.
5:55 Beam is back and stable - started run 3164.
6:30 No beam - MCC said they had the same problem as earlier so they took the beam away.
6:44 Beam's back (--> run # 3165 )
