<b>Accelerator Status:</b>
<ul>
  <li>Beam has been very stable. Issues have been from owr side this time. 
  <ul>
    <li> See <a href="https://logbooks.jlab.org/entry/3917677">Oct 04 Day Beam Summary</a>,  <a href="https://logbooks.jlab.org/entry/3918024">Oct 04 Swing Beam Summary</a>, <a href="https://logbooks.jlab.org/entry/3918164">Oct 05 Owl Beam Summary</a>  </li>
  </ul>
</li>
<ul>
  <li> Today, Ops is doing maintenance work from 09:00 to 13:00. During this time, there will be no beam into the Hall and any pending work can get done. <br> <b>Beam recovery is expected to start at 13:00 (this is NOT the time when Halls should expect beam)</b> </li>
</ul>
</ul>

<b>General Hall C Status:</b>
<ul>
  <li> Oct 04 Swing (yesterday): 
  <ul>
    <li> At 13:24, there was an HMS Dipole Interlock alarm <a href="https://logbooks.jlab.org/entry/3917638">HMS Dipole Interlock</a>. Contacted Amy Comer, but nothing could be done remotely. <br>
      She contacted Joe Beaufait and he went to the Hall with RADCON to check the problem. Joe and Ellen managed to temporarily fix the issue by by-passing a flow switch which caused MPS interlock <a href="https://logbooks.jlab.org/entry/3917784">HMS Dipole Fixed</a></li>
    <li> At ~19:57, SHMS Q1 went into interlock <a href="https://logbooks.jlab.org/entry/3917905">SHMS Q1 Interlock</a> and I contacted Ellen Becker (the new magnet expert on-call). Ellen went into the Hall and fixed the issue (low voltage power supply failure). She also went ahead and fixed a minor issue with the HMS Dipole ITrue readback <a href="https://logbooks.jlab.org/entry/3917965">SHMS Q1 Interlock Fixed</a>  </a></li>
  </ul>
</li>
  <li> Oct 05 Owl/Day (today):
  <ul>
    <li> At 07:34, I was informed about <a href="https://logbooks.jlab.org/entry/3918179">SHMQ Q1 Interlock</a>. Contacted Ellen and she will need to go into the Hall. Shift crew has requested a full survey of the Hall so that Ellen can have <br>
      more time to look at issue more in-depth in both the HMS as well as SHMS magnets, as interlocks have been more frequent. Accelerator will also be down during this time (starting at 09:00 am) for maintenance.
    </li>
<li> After beam studies conclude today and beam is restored to Hall C after beam recovery, BCM calibrations will get done sometime in the afternoon (TDB). We should let Hall B know beforehand, as these will be invasive to them. </li>
  </ul>
</li>
</ul>
																										
																										
<b>Hall C PION-LT Data Collection/Analysis Status:</b><br>
<ul>
  <li> As of 07:27 today (Owl Shift), we have accumulated: 1975 pions (19.75 %) (thanks Richard) </li>
</ul>

We will have brief RC Daily Meeting today at 10:00 am to discuss plan on moving forward.
