Current Status
- Q2=3.85, W=3.07, x=0.31, low epsilon, HMS angle=35.12 deg, HMS momentum = -1.332 GeV/c, SHMS angle= 8.39deg, SHMS momentum=-6.538 GeV/c;
- Summary of data and plans forward
- At end of Sat owl had around 2500 pions for the present setting.
- Will switch to SHMS angle= 6.39deg at 1pm this Saturday. Steve Lassiter has been notified
- Checked SHMS angle GUI/Camera: 8.400/8.385 . Steve will update GUI to match Camera before the move.
Current Run Plan
- Day :
- Until 1pm run Q2=3.85, W=3.07, x=0.31, low epsilon, HMS angle=35.12 deg, HMS momentum = -1.332 GeV/c, SHMS angle= 8.39deg, SHMS momentum=-6.538 GeV/c;
- Rotate SHMS to 6.39 deg
- 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 a FADCmode 10 run
- 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;
Notices in Effect for Shift Crew
- The Raster Coil pair Ax and Ay are off. Raster needs to be at 4x4.
- Reduced the SHMS dipole LHE Lo alarm to 50 and LOLO alarm to 45.
- With LHe alarms it is good to check the cameras for plumes.
- 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
Planned Accesses to the Hall
- none
Planned Accelerator Configuration Changes
- none
Special Requests
- Plan to do the BCm calibration on Tues at 2:30
