Follow up Notes on Previous Shift

========================================================================
Items to Follow up on Next Shift

Pay attention to NMB2S ramp, Some indication that
there is an intermittant problem

Pay attention to the blue ice around the bubbler and monitor
temperature for the next few hours.

Many slow DAQ processes seem to stop spontaneously.
Keep an eye on during the next shift.
