Go back to Daily Run Plan Daily Run Plans
- General considerations
- Last night, MCC had a trouble by beam los at 3C00 BLM till around 11PM.
- After reconstructed optics beam line, we had 10uA for some production runs during OWL.
Specific mission
- Note: MCC RF recovery (8:30-11:30AM) Down time
1/ Doug: Series of magnet measurement <: 1hr / no beam/ but beam permit
Bdl vs. current (decreasing magnet 375A->0A by 25A)
- No controlled access !
Once RF recovery is done,
2/ BCM calibration (high beam current 30uA(60 ideal) with FC & empty target)
Instruction:
DOC1DOC2
- Experts will perform this (Dave/Julie/Thir/...)
- Calo. HV off
- If beam is not stable nor acceptable (30uA), we may skip this and go to 3/
3/ Set up beam through Compton chicane
- Dave starts to turn on laser for warming up
4/ Production Data with stable beam current
- Detailed instructions here
Upcoming event(Long Term)
- Beam study (Thursday, 3/10)
- Target boiling test (60uA)
BPM/Spot++ Check
- After beam lost for considerable time (like beam study, pass change,...)
- Ask MCC to run 5uA wth carbon hole target and make sure you can see the hole through Spot++
