RC Updates

Summary of swing 11/20 - day 11/21

• Productive swing and owl shifts to collect good fraction of data on polarized He3 target @45uA beam current with prescale: ps1=9, ps2=15, ps3=0, ps5=3 and all other -1
• No major issue on DAQ during this time
• South Linac went to controlled access after MCC meeting to repair turbo pumps (no estimation provided)

Short term run plan

• Continue production data taking on polarized He3

1. 45uA of beam current | Use ps3=0, ps5=3, ps2=15, rest =-1 | One hour long runs
2. Move the target to the pickup coil position, and do NMR sweep around every 3 hours
3. Return to step 1

• Consideration to increase beam current to 50uA during tomorrow day shift

Issues

• Dump right Ion chamber cabling needs to be changed (Jerry Kowal is aware of it)

Hall Access List
