<h2>Accelerator and Hall Status</h2>
<ul>
<li>Another very productive day! Collected <b>1.33 C</b> on LH2. </li>
<li>Beam continued to be stable and DAQ had less than usual number of crashes.</li>
<li>Early day shift, the ECAL AC Unit 1 turned itself off again. Arun and I made a quick escorted access around 11am to reset it. <a href="https://logbooks.jlab.org/entry/4388223">https://logbooks.jlab.org/entry/4388223</a> </li>
<li>Around the same time, there were some communication issues with a few EPICS PVs related to ECAL and GEMs, which were resolved by rebooting the corresponding IOCs. Thanks to Bill, Arun, Ching Him, Jhih-Ying, and Don. <a href="https://logbooks.jlab.org/entry/4388200">https://logbooks.jlab.org/entry/4388200</a>, <a href="https://logbooks.jlab.org/entry/4388273">https://logbooks.jlab.org/entry/4388273</a> </li>
