<p>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.<br />
Production running on the LH2 target continued until 15:30, when the experiment began taking two hours of data on the 15 cm<br />
dummy target. After the first hour was completed, the left HRS DAQ failed due to a reported "Disk Full" error. Some old .tmp<br />
files were removed, but the disk associated with adaq1 were far from full. We also noticed that there were several Start-of-run<br />
and a few End-of-Run Halog entries that were completely empty: <a href="https://logbooks.jlab.org/entry/3402753">https://logbooks.jlab.org/entry/3402753</a><br />
However, the EPICS files themselves were properly created and written to the adaq home directory. Data taking was resumed,<br />
and no more problems were seen from this issue.</p>
<p>Production data on the LH2 target resumed at 18:00 and continued through Owl shift at 40 uA. The electron beam went off this<br />
morning at 06:00 as planned for the scheduled down period. A radiological survey of Hall A was completed, and Hall A was taken<br />
to restricted access around 08:30. Around this time, Dave Meekins started working on the cryo-target, which will be warmed up<br />
today. Pointing surveys will be conducted for both spectrometers either as early as this afternoon or no later than the middle of<br />
this week.</p>
<p>We expect beam back sometime in October for the next round of DVCS and GMp running!</p>
