<p>Maintenance day started at 6 a.m. as planned yesterday the hall went into the controlled access. The lock of the accelerator and Halls happened around 4 p.m. Beam restoration lasted longer than expected, and CW was established around 3 a.m. We took data when the beam was available. </p>
<p>Items addressed from our side inside of the Hall:<br />
1. Heidi replaced an N2 pressure sensor. Thermal hotspot Camera was checked?<br />
2. Jerry and others worked on the pump on top of the HMS<br />
3. Ellen went into the hall to check various cryocomponents.<br />
4. AC work in the CH completed</p>
<p>Items addressed from our side of the Hall:<br />
1. Alex and Hanjie completed the DAQ computer transfer, the DAQ was verified with LED data taking. The 50k replay script works. Alex is confident with a 10% higher current.<br />
2. Bob worked on the scaler.<br />
3. Bill Henry worked on repairing the alarm handler. (Starting the DAQ no longer generates the warning on the alarm handler.)<br />
4. Peter verified the new changes for the hcana, message to Mark: "Please go ahead and commit the changes".</p>
<p>Issues:<br />
1. Newly failed NPS modules: <a href="https://logbooks.jlab.org/entry/4209099">https://logbooks.jlab.org/entry/4209099</a><br />
2. NPS LV due to the broken PMTs in column 2: <a href="https://logbooks.jlab.org/entry/4209048">https://logbooks.jlab.org/entry/4209048</a><br />
3. Lost communication with the raster IOC: <a href="https://logbooks.jlab.org/entry/4208767">https://logbooks.jlab.org/entry/4208767</a><br />
4. Alarm handler no warning? <a href="https://logbooks.jlab.org/entry/4209113">https://logbooks.jlab.org/entry/4209113</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>
