RC Meeting Information
RC Daily Meetings are at 4:15 PM, remote
Wednesday Aug 13 2020.
General updates
Pending problem
- Beam trip rate
Recent polarization measurements
Current Run Plan
Normal Production running
- Prerequisites
- Make sure operational restrictions are followed.
- Make sure the raster size is correct (4-4.5)
- Monitor beam parameters/configuration very often and post an entry like this at the beginning of your shift and when run conditions have changed
- Running on cell targets: raster always ON (4-4.5, size will be determined by the scraping checks), orbit locks ON, current ramp rate 1 muA/sec
- Always take 120Hz of EDTM
- Fill the BTA with realistic numbers. If the desired beam current is not delivered prorate your ABUs!
- Change the IHWP every 4 hours when running on glass cells
- Run plan
- Since we have been down since 9 am, we likely want to start back with the Beam / Raster checkout (short procedure)
- Production on 3He; if not able to reach requested current, pro-rate the ABUs
Notes for tomorrow's 7:45 meeting
Future
- We are on the schedule to switch to 1st pass on the week of Aug 24 (Monday/ Tuesday). Need about ~ 3 days at 1st pass and would like to switch back to 5th pass before the weekend.
- EPR diode good for now, but check for future planned accesses.
- If Hall will have opening for 1+ hours, let Simona know as there is work to do on the cerenkov.
