The LHRS shield house temperature stays constant at 80.0 F since yesterday morning. We are still monitoring the situation, but for today there seems to be no action necessary.<br>
<br>
Yesterday was running quite smoothly. <br>
Day shift collected 1.9C with avg. efficiency ~65%<br>
Swing shift collected 2.5C with avg. efficiency ~70%<br>
Owl shift collected 2.6C with avg. efficiency ~71%<br>
In total we collected 7C and finished slugs 162 and 163. slug 164 is currently ongoing.<br>
<br>
We had no beam for approx. 2 hours in the afternoon (2:30pm to 4:30pm) most likely due to a drop of substation power (see https://logbooks.jlab.org/entry/3802145). At the same time LHRS dipole tripped (see https://logbooks.jlab.org/entry/3802145, https://logbooks.jlab.org/entry/3802171)<br>
Today we lost beam at ~6:40am (see https://logbooks.jlab.org/entry/3802566) and still waiting to get the beam back. After brief update from the Crew Chief we expect beam at ~10:30am. <br>
<br>
The plan is to continue with production as soon as the beam is back. In addition, we have scheduled an unser calibration for today.<br>
<br>
Open issues:<br>
monitor the LHRS shield house temperature<br>
<br>
ROC6 was crashing at least once during a shift yesterday<br>
<br>
We still have some open shifts to be filled:<br>
saturday march 14: owl TO<br>
saturday march 14: day SL<br>
sunday march 15: day SL<br>
sunday march 15: day analysis<br>
monday march 16: owl analysis<br>
monday march 16: day SL<br>
wednesday march 18: owl SL<br>
<br>
During todays morning 8am PD summary meeting it was mentioned: "I noticed that despite having ~24 more minutes of beam over the other halls, Hall A reported significantly less ABU+BANU than other halls." (see https://logbooks.jlab.org/entry/3802609). We should address this issue during the RC meeting this afternoon.<br>
<br>
We will have our usual meeting upstairs in the counting house at 3:15 PM today. Bluejeans link for remote participants: https://bluejeans.com/256205934<br>
