<div class="logentry node-content">
<p>Yesterday, we were down for the PSS work in the BSY.<br />
We used this time to take LED and cosmic data.</p>
<p>Last night, around 22:50, we got the CW beam and started continuing elastic calibration data.<br />
The beam was good and ran smoothly overnight.</p>
<p>Today, we are planning to complete the elastic calibration data taking and proceed to BCM calibration.<br />
The deadtime and target boiling studies will be performed after that. The run plan will be discussed during today's RC meeting.</p>
<p>Tomorrow, MCC will perform some beam delivery tests from 3:00 -7:00 a.m., and the accelerator maintenance.<br />
During this time hall will be surveyed and will be put in controlled access ~ 9:30 -10 am.</p>
<p>Some planned work during tomorrow's downtime:<br />
Brad Sawatzky will pull an image of the go_cmagnets virtual machine. This may take 1-2 hours. During this time the remote control for the spectrometer motion control will be down.<br />
Brad will coordinate this with the shift workers. Please let Brad and me know if you have any concerns or objections to this.</p>
<p>Heidi and Hall Techs will be working in the hall for some vacuum issues.<br />
Calorimeter Work: Some repair work for some low-amplitude channels. Maybe some fiber replacement if we get the optical fiber delivered by tomorrow morning.</p>
<p>Please let me know if you want to perform any repair or maintenance work inside the hall tomorrow.</p>
<p>Shifts:<br />
We urgently need some Owl shift workers for some upcoming shifts.<br />
Please consider signing up for the open slots (<a href="https://misportal.jlab.org/mis/apps/physics/shiftSchedule/index.cfm?experimentRunId=DVCS-NPS-2023">https://misportal.jlab.org/mis/apps/physics/shiftSchedule/index.cfm?expe...</a>).</p>
<p>There will be the usual RC meeting today at 11 a.m. Zoom information is below:</p>
