-# 0:20 We notice a very low counting rate (about 24Hz) and stop/starts another the
run; a few minuts later, ROC14 dies and we rebooted it; no longer problem (up to
the next one...).
-# 0:30 Start increasing the current to 80 uA
-# 1:30 Problems with ROC1 / kcoda etc...
-# 2:44 Start increasing the current to 90 uA
-# 3:12 Q3 of the right arm tripped / too low helium level (about 30%)
-# 3:26 Q3 is now okay and cycled / data taking continues
-# 5:53 MCC takes beam for QE measurement
-# 6:10 Beam is back / Acquisition crashes
-# 6:23 Data taking continues
-# 7:07 Beam off / Linac problems
