[Halla_running] [New Logentry] RC Report for Monday, April 25

The last day of the run period was reasonably productive, though the beam current was still limited to 40-45 uA most of the time.
Production running on the LH2 target continued until 15:30, when the experiment began taking two hours of data on the 15 cm 
dummy target.  After the first hour was completed, the left HRS DAQ failed due to a reported "Disk Full" error.  Some old .tmp
files were removed, but the disk associated with adaq1 were far from full.  We also noticed that there were several Start-of-run
and a few End-of-Run Halog entries that were completely empty: https://logbooks.jlab.org/entry/3402753
However, the EPICS files themselves were properly created and written to the adaq home directory.  Data taking was resumed, 
and no more problems were seen from this issue.

Production data on the LH2 target resumed at 18:00 and continued through Owl shift at 40 uA.  The electron beam went off this
morning at 06:00 as planned for the scheduled down period.  A radiological survey of Hall A was completed, and Hall A was taken
to restricted access around 08:30.  Around this time, Dave Meekins started working on the cryo-target, which will be warmed up 
today.  Pointing surveys will be conducted for both spectrometers either as early as this afternoon or no later than the middle of 
this week.

We expect beam back sometime in October for the next round of DVCS and GMp running!
