Description of Shift:

run spill time comment
------------------------------------------------------------------------
14653 01:48 Beam disappeared, SY energy conservation.
01:68 Beam is back
02:18 Lost beam for good!

03:05 LRF problems, experts enroute, no estimate.
03:10 AA disabled/adjusted the two erratic SDAQ low
voltage errors after consulting with the experts.
All the buttons are green, please don't ignore the
errors.
03:10 Call MCR to get an estimate, forced the guy to say
at least one hour so that we could take a laser
scan. He said so!
396 03:12 Stop the run.

14653 03:20 Long laser scan started.
04:10 Laser scan ends. Initialize the next 799 run.
04:20 VJ loaded new FERA peds.
14654 06:25 Start the run and wait for beam.
06:45 The '03:05' message is invariant. MCR says at
least another hour but don't know for sure.
