Here are some notable things that have happened since yesterday, and the short-term run plan:
<ul>
<li> Data collection proceeded smoothly throughout yesterday's day and swing shifts, as well as most of today's owl shift. At around 5 am, shift workers realized that they were unable to adjust the SHMS magnet current while attempting to change kinematic for pi- setting. The Hall C engineers investigated the issue and determined that escorted access was required to resolve it.</li>
<li> While waiting for the engineers to arrive at 8 am, we collected Cu and LD2 data for z=0.5 kinematic setting. </li>
<li> Hall C engineers then took an escorted access to fix the SHMS magnet control. </li>
<li> Currently, Dave Gaskell is setting up for the Moller polarization measurement. </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/4444366"> yesterday's day </a>, <a href="https://logbooks.jlab.org/entry/4444687"> yesterday's swing </a>, and <a href="https://ogbooks.jlab.org/entry/4444849"> and today's owl </a>. ABU for last 24 hours – 17.5 hours. Actual Beam in the Hall 19.7 hr.</li>
<li> <span style="color: #ff0000;"> We have a few open shifts and tread requests next week. Please sign up if you can. <a href="denied:”https://misportal.jlab.org/mis/apps/physics/shiftSchedule/index.cfm?experimentRunId=HALLC-RSIDIS”"> Shift signup page </a></span></li>
