EVENTS

------

16:07   evacuate D2 reference cell

17:10   start N2 calibration runs

18:45   go to pol. He3 production running

19:30   HAPPEX and Right-HRS DAQs die because adaql1 freezes, restore all

20:00   resume production

21:36   beam off, power supply trip in one of ACC magnets

23:20   MCC sends us pulsed beam, we switch to BeO target

23:25   "not-so-long-beam-off" recovery procedure

23:37   target lasers OFF/ON briefly to see beam spot on BeO

23:50   resume production
