<p>RC Report 15 April 2025</p>
<p>Pretty good last 24h.<br />
Mostly data taking at 0.3uA on LD2.<br />
During Swing we got some DAQ issues and GEM trips. DAQ was reset and GEM trip limits slightly adjusted (<a href="https://logbooks.jlab.org/entry/4356712">https://logbooks.jlab.org/entry/4356712</a>).<br />
During Owl and Day the HMS Q3 tripped several times. All times reset was possible remotely. This will be investigated tomorrow during access. Ellen believes that the water supply is close to trip limit.<br />
Bill solved the double peak reference time issue from yesterday (<a href="https://logbooks.jlab.org/entry/4357129">https://logbooks.jlab.org/entry/4357129</a>). It was due to EDTM being on. It is off now for data runs.<br />
At 1:30 we will do our BCM calibration.</p>
<p>We will have the regular RC meeting, at 2:30pm EDT. Online information here -> <a href="https://logbooks.jlab.org/entry/4346862">https://logbooks.jlab.org/entry/4346862</a></p>
<p>SHIFT SUMMARIES:<br />
- Day: <a href="https://logbooks.jlab.org/entry/4356083">https://logbooks.jlab.org/entry/4356083</a><br />
- Swing: <a href="https://logbooks.jlab.org/entry/4356408">https://logbooks.jlab.org/entry/4356408</a><br />
- Owl: <a href="https://logbooks.jlab.org/entry/4356698">https://logbooks.jlab.org/entry/4356698</a></p>
<p>RUN PLAN<br />
- Take data on LD2 at 0.3uA with GEM and LAD, DAQ setting: Production, During day shift take one data with only SHMS and HMS trigger respectively.</p>
<p>OPEN ISSUES<br />
- shifts to cover in the next days<br />
- no NMR lock. Dave got a quick lock (<a href="https://logbooks.jlab.org/entry/4356028">https://logbooks.jlab.org/entry/4356028</a>)<br />
- Several HMS Q3 trips over the last days --> checked tomorrow during access<br />
- SHMS angle encoder position is wrong --> we can correct tomorrow<br />
- Define analysis cuts to estimate counts<br />
- GEM tracking (<a href="https://logbooks.jlab.org/entry/4355541">https://logbooks.jlab.org/entry/4355541</a>)</p>
