Here are some notable things that have happened since yesterday, and the short-term run plan:
<ul><li> We were planning to go to controlled access to work on the water leak on the chiller at 10 am. But, the chiller stopped chilling around 9:20 am. We requested for an earlier hall survey. Thanks RadCon for their support. <a href="https://logbooks.jlab.org/entry/4286178"> Chiller problem </a> </li>
<li>Here is the <a href="https://logbooks.jlab.org/entry/4286247"> chiller work update inside the hall.</a> Unfortunately, the fix didn’t work and we are planning to work on this again today during the pass change <a href="https://logbooks.jlab.org/entry/4286440"> Chiller status at the end of the day. </a> We decided to run over night with it and complete elastic calibration for this pass.</li>
<li>While we were waiting for the leak sealant to dry, we performed BCM calibration <a href="https://logbooks.jlab.org/entry/4286409"> BCM calibration. </a> </li>
<li>Since the NPS temperature took some time to stabilize, we deferred the elastic calibration and took a luminosity scan for cross-calibration. <a href="https://logbooks.jlab.org/entry/4286450"> Lumi scan</a> </li>
<li>Elastic calibration started at the end of the swing shift and continued until MCC stopped the beam for pass change. <a href="https://logbooks.jlab.org/entry/4286960">A quick result of the elastic calibration. </a> </li>
<li> Shift worker found the Isoporanol temperature is zero. <a href="denied:”https://logbooks.jlab.org/entry/4287046”"> gas temp </a></li>
<li>Here are the last three shift summaries from <a href="https://logbooks.jlab.org/entry/4286282"> yesterday's day </a>, <a href="https://logbooks.jlab.org/entry/4286477"> yesterday's swing </a>, and <a href="https://logbooks.jlab.org/entry/4286834"> and today's owl </a>. ABU for last 24 hours - 14.4 hours.</li>
<li> We will perform the elastic calibration after we get the beam until tomorrow morning. Then we will move the SHMS spectrometer as well as the NPS calorimeter. We need Tech support tomorrow for the
SHMS rotation as well as NPS movement.</li>
<li> <span style="color: #ff0000;"> Tomorrow day shift TO slot is still open. Please sign up if you can. <a href="https://misportal.jlab.org/mis/apps/physics/shiftSchedule/index.cfm?experimentRunId=DVCS-NPS-2023"> Shift signup page </a></span></li>
</ul><br />
Updates from 8 am MCC meeting:
<ul><li> Expected beam delivery sometime during swing.</li>
<li> MCC will perform a BLA calibration. This would allow them to send 40 uA to Hall C.</li>
<li> Beam study is scheduled for Thursday. Hall C is not required for this. </li>
</ul><br />
We will have a regular RC meeting at 11:00 am today in the CH conference room.
