<p>Smooth running in the past 24 hours in terms of beam delivery. Moller measurement started at 10 a.m. this morning as expected. And projected finishing time is 4 p.m.<br />
Looking into the next week, there will be a scheduled maintenance downtime next Wednesday, we should plan on how to profit from this to service the detector, activities including base removal/swap, Radiation monitor replacement, shielding installation, and special test.</p>
<p>Many thanks to the Hall experts, quite a few issues were addressed in the past day:<br />
1. Thanks to Bob's effort, the scalar is now displaying in between the runs. This is a significant time-saver especially during the part of the run plan when the PS needs to be changed every 20 minutes. (Thanks Bob)<br />
2. DAQ seems to be able to handle 20% higher right, LD2 runs are currently running at 12 uA (instead of 10 uA from the previous day.)<br />
3. 8pm, DAQ crashed in the middle of the run, Alex was contacted to the restoration. (Near future protocol on DAQ issues, Bob is the on-call for the DAQ issues).<br />
4. 10 am, HMS Colimator GUI got stuck, reset procedure was attempted, and hall access was requested to manually reset the IOC: <a href="https://logbooks.jlab.org/entry/4209134">https://logbooks.jlab.org/entry/4209134</a><br />
5. 23 pm, The HMS Q3 software interlock tripped, and lost current, the experience shifter was able to clear the interlock and resume production: <a href="https://logbooks.jlab.org/entry/4209643">https://logbooks.jlab.org/entry/4209643</a> </p>
<p>A few new/raised concerns:<br />
1. During the DAQ Coda configuration changes, the instruction is very unclear if a "RESET" procedure is needed. We need to make the wiki instructions clear on this part. Because of this ambiguity, we potentially might have lost 1 good run on this.<br />
2. Part of the run plan requires changing setting, and beam current, frequently, as a result, the run sheets are not completely filled.<br />
3. DAQ crashes during the run-ending process, in this case, the Run End log is not generated. It is not clear how to keep records for such runs </p>
<p>Sweeper off test results:<br />
1. LD2, 12 uA, Strip chart: <a href="https://logbooks.jlab.org/entry/4210027">https://logbooks.jlab.org/entry/4210027</a><br />
2. LD2 Sweeper on: <a href="https://logbooks.jlab.org/entry/4209547">https://logbooks.jlab.org/entry/4209547</a><br />
3. LD2 Sweeper off: <a href="https://logbooks.jlab.org/entry/4209596">https://logbooks.jlab.org/entry/4209596</a><br />
4. Sweeper run 2272: <a href="https://logbooks.jlab.org/entry/4209605">https://logbooks.jlab.org/entry/4209605</a></p>
<p>Plan for the near future:<br />
1. Continue production<br />
2. Half wave plane change at 11 a.m.<br />
3. Moller measurement starting 8:30 a.m., last Friday for the day shift.</p>
<p>There will be an RC meeting at 11 a.m today.</p>
