RC Summary October 19:

Yesterday, we were down due to repairs of Arc9. Chris took the time to perform a TE measurement on the NH3 target.
Beam came back around 8.30pm, harp scans looked good and by 9:30pm we were back in production mode with 1/2 plate OUT.
Target polarization reached -74% maximum.

We collected about 100M triggered events with 1/2 plate OUT. Some of the data seems to have MVT off for a while (see https://logbooks.jlab.org/entry/4063057).

During the DOE accelerator tour today, we took the time to change target to ND3, repair magnet beacons and exchanged broken CND CFD module (https://logbooks.jlab.org/entry/4063234, https://logbooks.jlab.org/entry/4063237, https://logbooks.jlab.org/entry/4063256).

We expect beam back late Day and early swing. We plan to do check beam on the tagger, do a  Moller run and then continue production on ND3

Best,
Florian
