<p>Waited for beam all day yesterday, but we managed to do EPR measurement:<br /><a href="https://logbooks.jlab.org/entry/4197658">https://logbooks.jlab.org/entry/4197658</a><br /><a href="https://logbooks.jlab.org/entry/4197666">https://logbooks.jlab.org/entry/4197666</a><br /><a href="https://logbooks.jlab.org/entry/4197679">https://logbooks.jlab.org/entry/4197679</a></p>
<p>Beam came back at 6PM, so we could finally do beam checkout.<br />
We found the optimal XSOF, YSOF positions: <a href="https://logbooks.jlab.org/entry/4198020">https://logbooks.jlab.org/entry/4198020</a><br />
We also scanned the carbon hole in X and Y:<br /><a href="https://logbooks.jlab.org/entry/4198040">https://logbooks.jlab.org/entry/4198040</a><br /><a href="https://logbooks.jlab.org/entry/4198057">https://logbooks.jlab.org/entry/4198057</a></p>
<p>Target polarization 42.3% at the end of the beam checkout:<br /><a href="https://logbooks.jlab.org/entry/4198063">https://logbooks.jlab.org/entry/4198063</a></p>
<p>Resumed production early owl, first with 10uA:<br /><a href="https://logbooks.jlab.org/entry/4198141">https://logbooks.jlab.org/entry/4198141</a><br />
and worked our way up to 45uA<br />
Target polarization after more than a shift of running: 40.1%<br /><a href="https://logbooks.jlab.org/entry/4198467">https://logbooks.jlab.org/entry/4198467</a></p>
<p>Also:<br />
Target rupture early Monday morning:<br /><a href="https://logbooks.jlab.org/entry/4195983">https://logbooks.jlab.org/entry/4195983</a><br />
Target replaced and aligned late Wednesday afternoon<br /><a href="https://logbooks.jlab.org/entry/4197304">https://logbooks.jlab.org/entry/4197304</a><br />
We lost essentially one additional day of beam compared to the two days schedule for a normal cell changeover, which is much less than formerly anticipated. Kudos to target group, radcon, hall a techs, and Gary (who coordinated everyone as RC);</p>
<p>We will have the regular RC meeting at 3:30pm in the Counting House conference room.<br />
