Current Status
- Steady beam and data taking over the weekend
- Finished the Q2=3.85 W=2.62 x=0.39 low epsilon data taking
- See the Status Page for more
- In controlled access for rotation at 10:00
- Rotation is done, at 5.50 degrees on the SHMS now
- This might be the last time we do this for many years, so I got a bunch of pictures
Current Run Plan
- After the rotation, we'll start data taking on the Q2=1.60 W=3.08 x=0.15 setting
- We are actually doing this in reverse (compared to the run plan)
- Start on Page 39 of the run plan
- Work backwards until we get to page 33
- Once page 33 is finished, we go back and finish the HeePCoin settings we didn't finish
- Start with HeePCoin #4 on page 16 of the run plan
- We'll see how progress on this setting is later today, shouldn't take more than a day or two
- BCM calibration is planned for tomorrow (likely around 11:30, after the RC meeting)
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
- Controlled access for rotation this morning, hopefully done by midday
- Will try to address some of the issues above today
Special Requests
- Fix coffee machine, or replace.
- BCM Calibration - Tuesday (23/8)
- Dave Mack posted the updated procedure
- Beam energy measurement - Wednesday (24/8)
