<p>Yesterday, we moved SHMS and HMS to 13.5 degrees. For the SHMS move we had to decable the GEMs, move it on the target platform and cable it. This was done successfully without any problems.<br />
Furthermore, Hanjie updated the VTP firmware with the recent changes from HallA which should increase the DAQ stability and get rid of PEB crashes (<a href="https://logbooks.jlab.org/entry/4406033">https://logbooks.jlab.org/entry/4406033</a>).</p>
<p>Also vaccuum pump for the can was kept running (<a href="https://logbooks.jlab.org/entry/4406155">https://logbooks.jlab.org/entry/4406155</a>) over night to improve the can vacuum. It will be removed today.<br />
We got beam back around 3 pm and took about 12h of ABUs on hydrogen at 0.6 and 0.3uA beam current</p>
<p>Around 7:45 Dave Meekings starting emptying the target and we took Carbon multifoil (+/- 10cm) in the mean time. This was completed around 8:30am (<a href="https://logbooks.jlab.org/entry/4406679">https://logbooks.jlab.org/entry/4406679</a>).<br />
Since 9am we are running on empty at 1.5uA since the GEMs and LAD tripped at 1.9uA (<a href="https://logbooks.jlab.org/entry/4406705">https://logbooks.jlab.org/entry/4406705</a>)</p>
<p>Plan for the day:<br />
===============<br />
Take 2h empty target runs<br />
11:00 Survey the hall and bring to controlled access for several hours for target change<br />
walkthrough by Sam at 1:30pm<br />
Move HMS back to 17 degrees.<br />
Heidi and Larry will remove pump and check can vacuum<br />
=============</p>
<p>=============<br />
We will have our regular RC Meeting today at CH conference Room and via zoom ( <a href="https://logbooks.jlab.org/entry/4346862">https://logbooks.jlab.org/entry/4346862</a>)<br />
