<p>Yesterday, Dave Meekins switched the gas in the LAD cell (Loop 3 ) to hydrogen (<a href="https://logbooks.jlab.org/entry/4405550">https://logbooks.jlab.org/entry/4405550</a>)<br />
Beam came back around 7.30pm and we took Harp scans and C-hole run. Everything looked good (see <a href="https://logbooks.jlab.org/entry/4405633">https://logbooks.jlab.org/entry/4405633</a>)<br />
We collected about 6h of hydrogen at 0.6uA during Swing and Owl shift and an additional 1h at 0.3uA.</p>
<p>The vertical separator went down around 5:15am for several hours so no more beam during the owl shift.<br />
As planned, Radcon surveyed the hall at 7:45am but hall went into lockdown due to door problems (<a href="https://logbooks.jlab.org/entry/4405976">https://logbooks.jlab.org/entry/4405976</a>). Therefore the hall is now in restricted access for the SHMS move and GEM repositioning.</p>
<p>Plan for the day:<br />
===============<br />
Move SHMS and HMS to 13.5 degrees<br />
Decabling, move and cable GEM due to SHMS move<br />
Heidi and technicians work on SHMS vacuum.<br />
=============</p>
<p>=============<br />
We will have our regular RC Meeting today at CH conference Room and via zoom,<br />

<p>Many Thanks to our shift takers for their hard work. We still need shift crews for the weekend Owl shift. Please consider signing up if you are available.<br />
