• 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;

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
