Current Status
- Steady beam and data taking so far over the weekend
- Q2=3.85 W=2.62 x=0.39 low epsilon LD2+ central setting done
- Q2=3.85 W=2.62 x=0.39 low epsilon LD2+ left setting - 6k pions (reduced from 10k goal)
- Q2=3.85 W=2.62 x=0.39 low epsilon LH2+ left setting - 6k pions (reduced from 10k goal)

- Weird prescalers set here for 4.5k pions - Jacob's Analysis Full Analysis Breakdown
Current Run Plan
- Finish off the Q2=3.85 W=2.62 x=0.39 low epsilon LH2+ central setting
- ~5k pions as of 11:00 on 21/8/22
- 10k target (~7-8 hours of good beam left to reach this)
- Go back to the Q2=3.85 W=2.62 x=0.39 low epsilon LH2+ left setting
- Get 2k more pions here (~4 hours)
- Q2=3.85 W=2.62 x=0.39 low epsilon LD2+ left setting after this if time permits
- Need another 2k pions here (~4 hours again)
Notices in Effect for Shift Crew
- If all SHMS magnets crash at the same time, push the SHMS dipole crash button (on the rack above the target heater manual controls and target temperature readbacks).
- For physics settings that come in quickly, please see - Analysis Note #1 Analysis Note #2
- Please see updated CoVID guidance for the weekend - Weekend CoVID Guidance
- Consult current issues posts below carefully
- Check for any indication that the collimator has moved in the 50k replays
- Check DC/Calorimeter plots in the 50k carefully
Current Issues
- Repeated weird white alarms
- Several things need rebooting during the downtime tomorrow
Planned Accesses to the Hall
- SHMS rotation to 5.50 on Monday (22/8) morning
- Beam off and call for survey at 08:00
Special Requests
- Fix coffee machine, or replace.
- BCM Calibration - Tuesday (23/8)?
- Dave M is going to provide an updated procedure.
- Beam energy measurement - Tuesday/Wednesday?
