<p>Yesterday was the accelerator maintenance day. Beam was taken off at 6 am Wednesday and hasn't been back. Most of the accelerator maintenance work went well as planned. However, the work on 2L22, 2L23 on the south linac are halted by EH&S due to an expired OSP. A new OSP has been prepared and is waiting for approval. Once the OSP is approved, it probably takes one hour to bring back 2L22, 2L23, then few hours to restore beam at south linac, then send beam into the hall. MCC estimates that the beam will be back during Swing shift </p>
<p>Hall C went into controlled access around 9:20 am on Wednesday and remains in controlled access. </p>
<p>Some notable things during Day shift:</p>
<p>Julie, Mitch, Wassim and Josh went into the hall swapped 625 pmt/base: <a href="https://logbooks.jlab.org/entry/4220990">https://logbooks.jlab.org/entry/4220990</a></p>

<p>A mysterious SHMS angle change in magnet GUI: <a href="https://logbooks.jlab.org/entry/4221181">https://logbooks.jlab.org/entry/4221181</a></p>

<p>During Swing shift, few LEDs runs haven been taken. One cosmic run is being taken since Owl shift.</p>
<p>When the beam is back, we will continue taking the elastic data for another 6 hours (beam on target).</p>
<p>There will be a RC meeting at 11 am: <a href="https://jlab-org.zoomgov.com/j/1617015555?pwd=L09IQ216dml6ZmM5ODExVjFsMX">https://jlab-org.zoomgov.com/j/1617015555?pwd=L09IQ216dml6ZmM5ODExVjFsMX</a>...<br />
