RC Meeting Information
RC Daily Meetings are at 11:00 (am) via Zoom and in person in the counting house meeting room (2nd floor)
- Zoom remote connection information:

Current Status
- Mixed data taking past 24 hours
- Q2=1.60 W=3.08 x=0.15 low epsilon running
- SHMS Centre (5.50) LD2+ - Done
- SHMS Left (7.50) LD2+ - [ Done]
- SHMS Left (7.50) Dummy Target - Done
- SHMS Left (7.50) LH2+ - After the arc energy measurement is done
- A couple of issues in the past 24 hours
- SHMS PSS dropped when rotating the SHMS to 7.50, SHMS hut door "open"?
- SHMS Q1 Vacuum spike
- Reminder, please follow the instructions on this!
- SHMS Q3 interlock
- SHMS Dipole interlock
- Beam quality overnight was a bit mixed, 2 hours down due to accelerator issues
Current Run Plan
- Arc energy measurement is ongoing
- After the arc energy measurement, run the Q2=1.60 W=3.08 x=0.15 low epsilon SHMS Left (7.50) LH2+ setting (page 33)
- Once this is done, finish HeePCoin #4 and #5 (pages 16 and 18 of the run plan), including dummy runs
- After HeePCoin, it's negative polarity time, we move to page 40 of the run plan and work our way through the last 9 pages of the run plan
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
- SHMS Q1 Vacuum Spikes - Follow the guidance
- Please see updated CoVID guidance in the recent CoVID guidance update
Current Issues
- SHMS Q1 Vacuum Spikes - Follow the guidance
- Weird polarity flip alarms still occurring
- More white alarms (BCM temp and raster again)
Planned Accesses to the Hall
- None planned yet
- Rotation to 6.00 degrees will be coming up (page 44 of the run plan)
- Given how long the next few settings are, this is likely going to be next week or later
Special Requests
- Fix coffee machine, or replace
- Rolf has the same supernatural abilities as Bill and has managed to fix it... for now.
- Beam energy measurement - Today! (24/8)
