Here are some notable things that have happened since yesterday, and the short-term run plan:
<ul>
<li> Yesterday, Dave Gaskell performed a Moller polarization measurement. <a href="https://logbooks.jlab.org/entry/4445406"> Here </a> is the summary, (polarization = -82.4 +/- 0.69%)</li>
<li> Since then we were taking production data for the pi- setting for z = 0.90. </li>
<li> RF recovery is scheduled for tomorrow. We are planning to put the Hall in controlled access. Please let the RC know if you want to do anything in the hall tomorrow. </li>
<li> Right now, beam is off for getting us prepared for the dry-run for the Secretary of Energy visit scheduled on Thursday. Larry and Heidi are planning to be in the hall opportunistically when the hall will be put in controlled access today.</li>
<li> The spokespersons have revised the run plan to maximize the physics outcome as we approach the accelerator shutdown scheduled for 3rd Sept. <a href="https://hallcweb.jlab.org/wiki/images/4/4c/R_SIDIS_Run_Plan_Summer_2025_JLab_v29.pdf"> Here </a> is the updated run plan . </li>
<li>Here are the last three shift summaries from <a href="https://logbooks.jlab.org/entry/4445103"> yesterday's day </a>, <a href="https://logbooks.jlab.org/entry/4445398"> yesterday's swing </a>, and <a href="https://logbooks.jlab.org/entry/4445656"> and today's owl </a>. ABU for last 24 hours – 7.5 hours (Moller polarization time isn't included). Actual Beam in the Hall 15.3 hr.</li>
</ul>
<br />
We will have a regular RC meeting at 2:30 pm today.
