Here are some notable things/issues that have happened since yesterday:
<br>
<br>
<ul>
<li>The work of emptying the sump was completed around yesterday at 19:40 hour. Thanks to all the people who worked hard to bring Beam back into hall A- <a href

<li>Received Beam authorization at 20:30 - <a href

<li>Complited harp scans and beam spot looked good - <a href="https://logbooks.jlab.org/entry/4223605"> Beam spot size </a> </li>
<li> Beam was down for some time due to a violation of operation restriction (unrastered CW beam on LD2 target of Hall C). Fortunately, they quickly resolved this and MCC started beam operation  - <a href ="https://logbooks.jlab.org/entry/4223643"> Restored beam operation </a> </li>
<li> Ion chamber calibration on the Carbon hole target -<a href ="https://logbooks.jlab.org/entry/4223682"> Ion chamber calibration </a>  </li>
<li> Around 3 am, there was a DAQ problem due to SBS GEMROC22. Eric and Alex resolved it.- <a href ="https://logbooks.jlab.org/entry/4223733"> DAQ problem </a> </li>
<li> Raster BRM issue needs to be looked at- <a href ="https://logbooks.jlab.org/entry/4223788"> Raster BRM issue </a> </li>
<li> Updated BPM XSOF and YSOF for the new target - <a href="https://logbooks.jlab.org/entry/4223908"> New Position locks </a> </li>
<li> Final beam position analysis from Bill - <a href="https://logbooks.jlab.org/entry/4223943"> Thanks Owl crew and Bill </a> </li>
<li> Performed ion chamber calibration for the reference cell and multifoil targets. </li>
<li> GEM experts will perform the GEM HV scan. After that, we will take one hour of production before going for Moller polarization measurement. </li>
<li> Don Jones prefers Moller measurement to start before 2 pm or after 8 pm. </li>
</ul>
