Current Run Plan

• Day : 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;
• Swing : 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;
• Owl : 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;
• The 3/4 trigger running will be done by the day shift.
• Need to do the AL dummy. SHould we do it this afternoon. How long?
• Called Steve Lassiter about angle change Sat afternoon

Notices in Effect for Shift Crew

• The Raster Coil pair Ax and Ay are off. Raster needs to be at 4x4.
• Can reduce the SHMS dipole LHE Lo alarmm to 50 and LOLO alarm to 45. Ask shift crew to do this.
• 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.
• Checked SHMS angle GUI/Camera: 8.400/8.385 . Need to remind Steve or Amy to update the GUI value to match the Camera before move.

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
