<br>
Here are some notable things that have happened since yesterday, and the short-term run plan:
</br>
</br>

<ul>
<li> We ran smoothly until 7 pm when the SHMS dipole interlocked <a href=”https://logbooks.jlab.org/entry/4442552”> hclog entry</a>. </li>
<li> It interlocked again on the lead flow when the shift workers tried to ramp it up again after clearing the interlock. <a href=”https://logbooks.jlab.org/entry/4442592”> SHMS dipole interlocked again</a>. </li>
<li> Heidi adjusted the <a href=”https://logbooks.jlab.org/entry/4442606”>  max lead follow </a> and that <a href=”https://logbooks.jlab.org/entry/4442639”> enabled us to set the SHMS magnet </a> for the desired kinematics. However, Heidi wants the flow controller to be replaced before the weekend. </li>
<li> After that, we ran smoothly overnight for the z=0.90 kinematic. Except one 15 min Cu run, we have completed data taking for this kinematic. </li>
<li> Currently, RadCon is surveying the hall, so that Heidi and her team can replace the suspected flow controller for the SHMS Dipole lead and hoping for a smooth running over the weekend. </li>
<li> We are planning to do a Moller polarization measurement on the coming Monday. </li>
<li> We will continue executing the <a href=”https://hallcweb.jlab.org/wiki/images/e/ee/R_SIDIS_Run_Plan_Summer_2025_JLab_v26.pdf”> Run plan </a>. </li>
<li> Here are the last three shift summaries from <a href="https://logbooks.jlab.org/entry/4442175"> yesterday's day </a>, <a href=" https://logbooks.jlab.org/entry/4442486"> yesterday's swing </a>, and <a href="https://logbooks.jlab.org/entry/4442752"> and today's owl </a>. ABU for last 24 hours – 10.9 hours. Actual Beam in the Hall is 16.1 hr. Hall down for 2 hour for SHMS interlock</li>

<li> <FONT COLOR=" #ff0000"> We have few open shifts next week. Please sign up if you can. <a
