Morning everyone, just a quick update today.
<br>
A brief outline of notable things since yesterday -
<br>
<ul>
<li> Towards the end of day shift, <a href="https://logbooks.jlab.org/entry/4214784"> there was an odd cryo hickup.burp</a>. This doesn't seem to have caused any issues but do keep an eye out.</li>
<li> We put <a href="https://logbooks.jlab.org/entry/4214821">the half wave plate in</a>, Paul also then ran the <a href="https://logbooks.jlab.org/entry/4214817"> flipper script.</a></li>
<li> Around the same time as the wave plate switch, Paul and Riad did their adjustments to the IA slope, <a href="https://logbooks.jlab.org/entry/4215130"> it looks like this didn't work</a>, see Paul's analysis in the linked entry. <a href="https://logbooks.jlab.org/entry/4215161"> Paul has also been monitoring the asymmetry since the HWP change.</a>
<li> <a href="https://logbooks.jlab.org/entry/4214832"> EDTM weirdness continues</a> and this could be tied to a wider <a href=https://logbooks.jlab.org/entry/4214957"> scaler issue</a>. I think this is worth discussing more in detail at our next meeting.
<li> We had a few <a href="https://logbooks.jlab.org/entry/4214966"> DAQ issues</a> but the shift crews largely <a href="https://logbooks.jlab.org/entry/4214977"> resolved these on their own.</a>
<li> This morning, Ed noticed some <a href="https://logbooks.jlab.org/entry/4215143"> odd behaviour with the HMS hodoscope</a>, however, on a different setting <a href="https://logbooks.jlab.org/entry/4215160"> this seemed to resolve itself</a>.
</ul> 
The only other notable issue was that we lost beam for ~6 hours overnight (from ~04:00 until ~09:30-10:00) due to a <a href="https://logbooks.jlab.org/entry/4215051">power glitch and subsequent recovery.</a>
<br>
We are back taking data now though. We'll continue running at this setting over the weekend, hopefully it'll be smooth sailing <span title = "and I don't say this just because Arsenal v Newcastle is on this afternoon.">for the rest of the day</span> and over the weekend.
<br>
We won't meet today and there's no plan for a meeting tomorrow unless something happens that needs imminent discussion. We will meet at 11:00 on Monday in the usual place and on zoom. We will formulate a plan for the maintenance day on Wednesday in that meeting.
<br>
Have a good weekend everyone!
<br>
<br>
