Current Status
- Jun 16 - Swing (yesterday)
- Received up to 25 uA of beam and did Carbon Hole check Carbon Hole (Raster ON), Carbon Hole (Raster OFF)
- started HMS optics studies
- Jun 17 - Owl (today)
- limited to 15 uA beam due to accelerator issues (Ops will work on Hall C line today to try and give us higher currents)
- completed the detector checkout part of run plan
- while doing +/-8 cm C12 optics run plan, HMS Dipole interlocked (~ 4:30 am )
- SHMS optics was taken instead in the meantime
- towards the end of Owl, HMS Q2, Q2 Dipole had all went to interlock
- Jun 17 - Day (today)
- S. Lassiter arrived and it currently in the Hall with Hall C techs working
- HMS Q1, Q2 Dipole interlocks
- HMS Dipole waterflow interlock explanation
- S. Lassiter ramped magnets back up and there seems to be OK now.
- S. Lassiter arrived and it currently in the Hall with Hall C techs working
Current Run Plan
- Complete Carbon Foil +/- 8 cm (part of HMS Optics plan)
- Complete Single Carbon Foil on HMS
- Do Coincidence Trigger Checkout
- Do single Heep coin setting
- Begin production physics
Notices in Effect for Shift Crew
- Please pro-rate ABU for 80 uA in beam time accounting. For example: 15/(max current limit) * ABU
Current Issues
Planned Accesses to the Hall
Planned Accelerator Configuration Changes
Special Requests
- S. Lassiter needs to put crush washers in LCW filters, so we may see a little bit of water by the HMS boogie for now, until he can put the washers next week, during maintenance period HMS Dipole LCW
- Xinzhan Bai request to go to restricted access to quickly swap MPD electronics out and check signals (~ 30 min.), whenever there is extended down (most likely during next accelerator maintenance period)
