Current Status

  • 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.
  • Rate estimeta and plans . RUn this setting until Saturday morning.
  • Yesterday's Day , Swing and Owl shift went smoothly. Current number of pions 2263

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.
    • BCm calibration at 2:30
  • 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
