Summary from Wednesday-Day (10/5/2022) to Thursday-Owl (10/6/2022)

General Summary:
- The NH3 target is ready polarized slightly above +78% according to NMR.
- No beam the whole day due to magnet RSEP8A down because of a cooling issue.
- Once it became clear that the beam would not be available for the swing and night shifts, the solenoid field was ramped-down and shifts were cancelled until the day shift (8am, Oct. 6th)

Events accumulated:
No event

Plan:
- Once we get the beam, do the beam recovery:
  -Harp scans (2C11 and 2C24). (Raster off, raster FSD masked, tagger on.)
  -Send 2nA beam to FCup, raster on, raster FSD on. Check beam positions 2H01, 2C24.
  -Ramp-up to 8nA
  -Check raster monitoring (to make sure we are not rastering on the edge of the cell).
-Do Moller run with 10 nA (please note that the manual say 4 nA but we do with 10 nA)
-Take production run with PROD66_PIN configuration for at least 20 M events
-Take run with normal PROD66 configuration. The duration for each run is 4 hours OR 100 M events
-Continue for ~24 hours then ask MCC to change the HWP to IN

We will have our regular RC meeting today at 2.00pm
