<p>Alive!! It's alive!! It's alive!!<br />
- Dr Frederick (or Froaderick) Frankenstein</p>
<p>Hope not to jinx, but after practically one month full of issues, I believe we had, and continue having, good hall behavior and smooth beam delievery. Accelerator was down since Thursday Swing shift until yesterday Swing.<br />
Dave M. completed the change of target to D2, finallizing the cooling down, practically, at the same time the accelerator was ready to deliver beam into the hall.<br />
In parallel, Heidi, Ellen, Steven Lassiter and Jamie Shiflett recovered HMS Q2 -> <a href="https://logbooks.jlab.org/entry/4376455">https://logbooks.jlab.org/entry/4376455</a><br />
Hall was swept ~18h, and beam checkout proceadure started at 18:15, finalizing at 21h. Production with D2 started at 21:10 and ran smooth until now.<br />
Only reported issues, but not new (<a href="https://logbooks.jlab.org/entry/4376640">https://logbooks.jlab.org/entry/4376640</a> and <a href="https://logbooks.jlab.org/entry/4372295">https://logbooks.jlab.org/entry/4372295</a>), are the LAD PMTs 02-00-10B and 02-00-08B which have been trip. After consulting Lucas, it was decided to reduce the HV.<br />
This morning (summary will be reported in tomorrow's report), Ching Him finished the HV GEM scans, on time before beam was taken down in order to address halo issues in Hall B.</p>
<p>SHIFT SUMMARIES:<br />
DAY -> <a href="https://logbooks.jlab.org/entry/4376310">https://logbooks.jlab.org/entry/4376310</a> and <a href="https://logbooks.jlab.org/entry/4376416">https://logbooks.jlab.org/entry/4376416</a><br />
SWING -> <a href="https://logbooks.jlab.org/entry/4376596">https://logbooks.jlab.org/entry/4376596</a><br />
OWL -> <a href="https://logbooks.jlab.org/entry/4377079">https://logbooks.jlab.org/entry/4377079</a></p>
<p>RUN PLAN:<br />
D2 production, at least until Monday</p>
<p>*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-<br />
Things are going well, why spoil them with a RC meeting? </p>
<p>Fun Fact of the Day:<br />
did you know, Paella, the famous Spaniard rice dish, NEVER, EVER has any kind of sausage (that includes chorizo), or eggs. You can call "rice with things in a paella pan", but not paella (trust me on this).</p>
