<div class="logentry node-content">
<p>Yesterday we had smooth data-taking on setting 2. There was a two-hour accelerator downtime during swing shift due to bad klystron for 1L10 <a href="https://logbooks.jlab.org/entry/4065504">https://logbooks.jlab.org/entry/4065504</a>, otherwise acceptable beam quality at 40 to 60 uA. </p>
<p>SHMS has been very happy except the Q2 trip this morning. Quickly resolved with the remote help from our magnet on call (Joe). CODA crashed a couple of times <a href="https://logbooks.jlab.org/entry/4065125">https://logbooks.jlab.org/entry/4065125</a><br />
During the Owl shift, shift worker was worried about SHMS S1Y rate higher than 1MHz. For the future reference, we need only to monitor S2Y rate and keep it less than 1MH) at the current angle setting (8 degree) .</p>
<p>HMS dipole LN2 level has been monitored for fluctuation : <a href="https://logbooks.jlab.org/entry/4065555">https://logbooks.jlab.org/entry/4065555</a></p>
<p>BCM04 and 05 gave a couple of yellow alarms. 04 had a white alarm in the midnight but quickly resolved by itself. <a href="https://logbooks.jlab.org/entry/4065758">https://logbooks.jlab.org/entry/4065758</a></p>
<p>There will be NO RC meeting today. Happy weekend, and please consider signing up for shifts next week.</p>
<p>Bests,<br />
