<br>
Here are some notable things/issues that have happened since yesterday:
<br>
<br>
<ul>
<li>Unfortunately, we didn't get authorization for the CW beam in Hall A yesterday swing - <a href

<li>Even if we had beam authorization, there would not have been any beam in the hall overnight due to the 2L22 cryomodule issue - <a href

<li>The SL for the last Swing and Owl shift were canceled. Today's Day's SL is in standby mode. TO reported since the last swing - the magnets and target LASER were on. Thanks to Jimmy, Eric, and Jackson for signing up for the shift on short notice.</li>
<li> Kate took cosmic runs with magnets on and produced HVs for production  - <a href ="https://logbooks.jlab.org/entry/4221624"> Production HV settings </a> </li>
<li> One hodoscope HV channel tripped -<a href ="https://logbooks.jlab.org/entry/4221632"> (halog entry from Jimmy) </a>  Gary is looking into it</li>
<li> Bill Henry performed a preliminary EPR calibration- <a href ="https://logbooks.jlab.org/entry/4221721"> EPR from Bill </a> </li>
<li> A further look on EPR calibration by Jackson- <a href ="https://logbooks.jlab.org/entry/4221724"> EPR from Jackson </a> </li>
<li> Hunter is at the CH to perform the FINAL EPR calibration </li>
</ul>

<br>
There are a couple of hours for work to pump ~180 gal of water from the swamp area in building 91 to a storage tank. 
After that, we most likely get the Beam authorization in the hall.
<br>
 Hopefully, by then the 2L22 cryomodule work will be complete.
<br>
We projected to start at some time in the swing at the earliest. 


<ul>
<li> The run plan from the spokesperson is attached. </li>
<li> Hall C is planning to perform a Moller measurement either Saturday or Monday. MCC doesn't prefer simultaneous Moller measurements in Hall A and C. So, we have to plan accordingly for the Moller measurement.</li>
<li> Yesterday, I contacted Ellen regarding whether BB magnet polarity can be changed remotely or not - her answer was NO. So, we should plan accordingly when to change polarity. </li>
</ul>

Thanks to all the people who signed up for the shifts on short notice.
<br>
There are still a couple of open slots. Please consider signing up for those open slots.
