Current Status
- Update on the current status for this setting
- Old Rate estimate and plans for this setting . RUn this setting until Saturday morning.
- Summary of data and plans forward
- Running production on LD2 Q2=3.85, W=3.07, x=0.31, low epsilon, HMS angle=35.12 deg, HMS momentum = -1.332 GeV/c, SHMS angle= 6.39deg, SHMS momentum=-6.538 GeV/c;
- 6uA was the best current for running at this angle.
- BCM calibration was done but limited to 43uA becuase of diffuser limits
- Yesterday's Day , Swing and Owl shift went smoothly. Current number of pions roughly 2900.
Current Run Plan
- Day :
- LD2 Q2=3.85, W=3.07, x=0.31, low epsilon, HMS angle=35.12 deg, HMS momentum = -1.332 GeV/c, SHMS angle= 6.39deg, SHMS momentum=-6.538 GeV/c;
- Need daily one hour trigger 3/4 runs.
- Swing
- LD2 Q2=3.85, W=3.07, x=0.31, low epsilon, HMS angle=35.12 deg, HMS momentum = -1.332 GeV/c, SHMS angle= 6.39deg, SHMS momentum=-6.538 GeV/c;
- Owl
- LD2 Q2=3.85, W=3.07, x=0.31, low epsilon, HMS angle=35.12 deg, HMS momentum = -1.332 GeV/c, SHMS angle= 6.39deg, SHMS momentum=-6.538 GeV/c;
- FADCmode 10 run 13695 taken on Saturday.
- Take the 2.5 hours Al dummy at end of running on Saturday morning.
Notices in Effect for Shift Crew
- The Raster Coil pair Ax and Ay are off. Raster needs to be at 4x4.
- With LHe alarms it is good to check the cameras for plumes. If no plume and it is below the LO alarm and above LOLO then monitor with a plot and halog the problem.
- With LNitrogen alarms are not that critical. Just need to start monitoring the problem with plot and halog.
Current Issues
- The Raster Coil pair Ax and Ay are off
- Elevator is not working
- Noticed bug in Prescale GUI
- Diffuser limit at 46uA
Planned Accesses to the Hall
- none
Planned Accelerator Configuration Changes
- none
Special Requests
- none
