17:02 ROC14 hanged. Lost about 5 minutes of beam time.
18:04 Finished Q2_k40; changed right arm to 58.42 deg and at 1.0745 GeV
19:20 Ready for Q2_l50. Will first do the optics run, then reduce beam
to 5 uA for harp run (with 9-fiol in place) before doing the
efficiency and then final production run.
19:50 Begin production run for Q2_l50.
20:05 We forgot to run trigsetup before Q2_l50 run begins. So, the
optics run (Run # 1833) and first (short) production run
(Run # 1835) may not be good. The first real good run is
Run # 1836. We will need to redo optics run at the end
after doing efficiency run.
20:28 MCC called to inform us that there was no beam due to
vacuum problem. They don't know how long will it take to
restore the beam.
21:00 Called MCC to find out the beam status. They still have no
idea as to when the beam will be back.
22:05 MCC called to let us know that they have found the problem.
Yet there is still no words as to when the beam will be back.
23:50 Left arm Q1 tripped off.
24:00 In the process of restoring left arm Q1. Still no sign of beam.
