<b>Accelerator Status:</b>
<ul>
<li>Sep 07/08 Swing/Owl (yesterday, today):
<ul>
<li> 2L18-4 Preventig filaments (16:34 - 17:06) <a href="https://logbooks.jlab.org/entry/3843341">2L18-4</a> </li>
<li> RSEP9A tripped off (22:21 - ~02:50) <a href="https://logbooks.jlab.org/entry/3843492">RSEP9A_trip</a> </li>
<li> Injector cavity 0L04-04 not making gradient (5:05 - 5:56) <a href="https://logbooks.jlab.org/entry/3843693">INJ_grad</a>, <a href="https://logbooks.jlab.org/entry/3843713">INJ_grad_follow-up</a></li>
<li> Injector OR region steering problem (6:21 - 7:42) <a href="https://logbooks.jlab.org/entry/3843716">INJ_OR_steering</a> </li>
<li> *Not the best Owl shift the accelerator has had in terms of beam delivery during Owl (~50 min only)* </li>
</ul>
</li>
<li>Sep 08 Day (today):
<ul>
<li> Accelerator working on trying to restore beam. As of 08:55, pathlength checked for Hall C beam and looks good. <a href="https://logbooks.jlab.org/entry/3843785">beam_pathlength_check</a></li>
<li> Beam restored to Hall C at ~ 09:00 </li>
</ul>
</li>
</ul>
<b>General Hall C Updates:</b>
<ul>
<li> Sep 07/08 Swing/Owl (yesterday, today):
<ul>
<li> Mingyu Chen updated the TO training slides with procedure for fitting pNMR, as there were issues with fitting program. See log-entry: <a href="https://logbooks.jlab.org/entry/3842395">pNMR_TO_update</a> </li>
<li> During Sep 07 Swing, d2n production continued at IHWP = IN configuration. We still needed ~50 min. of "beam-on-target" before the next IHWP change, which we were able to obtain during Owl.</li>
<li> What are "acceptable" beam profile check (Harp scans) parameters? How much can we compromse with? Will bring up at RC meeting today. <a href="https://logbooks.jlab.org/entry/3843675">Harp_scans_Sep08_Owl</a> </li>
<li> Beam Current History during Sep 07/08 Swing/Owl: <a href="https://logbooks.jlab.org/entry/3843546">Sep07_Swing</a>, <a href="https://logbooks.jlab.org/entry/3843769">Sep08_Owl</a> </li>
</ul>
</li>
<li> Sep 08 Day (today):
<ul>
<li> As of 09:05, Hall C is receiving tune beam. Beam profile checks --> <a href="https://logbooks.jlab.org/entry/3843795">IHA3H07A</a>, <a href="https://logbooks.jlab.org/entry/3843797">IHA3H07B</a> </li>
<li> Will proceed wil Pol He3 scraping checks and and start d2n production for ~480 min at the IHWP = OUT configuration. </li>
<li> MCC 7:45 meeting NOTE: PD (Jay) informed Ops will need to sent beam to C as part of beam studies (Sep 08 Swing, 16:30 - 19:30). We will need to be in no "No Target" position during beam studies.</li>
<li> During beam studies today at Swing, we plan to do target temperature tests (target expert, Junhao Chen) which is expected to take ~3-4 hrs. Then we will spin-up the target to 270 deg and take d2n reference cell data
until ~40 polarization is achieved to start taking d2n Pol He3 production data.</li>
</ul>
