A quick update for today.

The n = 1.011 Aerogel tray was installed successfully yesterday during the day shift - https://logbooks.jlab.org/entry/4031032 - Thanks to everyone involved for getting this done smoothly.

After the install, we made good progress on the Q2 = 2.73, W = 2.63, x =0.3114, low epsilon setting.

The physics rate was a bit lower than expected here so it took slightly longer than planned. However, as of 08:20 this morning we were done with this kinematic -

https://logbooks.jlab.org/entry/4031242 - SHMS Right
https://logbooks.jlab.org/entry/4031243 - SHMS Centre
https://logbooks.jlab.org/entry/4031310 - SHMS Left

There was one fairly minor issue overnight, for the central and left dummy runs, FADCMode10 was still enabled. This doesn't look like it will pose any issues but we'll discuss this briefly in the meeting.

We've now moved on to the Q2 = 3.85, W = 2.62, x = 0.3915, low epsilon setting. This one is pretty long, we'll probably be here all weekend.

So long as that goes smoothly, we'll proceed with the SHMS rotation to 5.50 degrees on Monday morning (22/8). This is currently scheduled in for ~09:00 (Beam off at 08:00 followed by a survey).

We'll also tentatively plan for the BCM calibration on Tuesday (23/8).

We'll have a meeting at 11:00 on zoom as usual -
