No RC meeting over weekend.

Next RC meeting at special time on Monday at 9:30 AM EST.
Connection information: https://bluejeans.com/861439920

Beam ran smooth over the rest of yesterday swing and Sat owl.


Present status
1) Production for 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= 8.39deg, SHMS momentum=-6.538 GeV/c;
2) At end of Sat owl had around 2500 pions for the present setting.
3) Will switch to SHMS angle= 6.39deg at 1pm this Saturday. Steve Lassiter has been notified
4) Checked SHMS angle GUI/Camera: 8.400/8.385 . Steve will update GUI to match Camera before the move.

Current run plan:
Day :
   1) 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;
    2) Rotate SHMS to 6.39 deg at 1pm. Contact Steve Lassiter
    3) Start running 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;
    3a) Need a FADCmode 10 run
    3b) Need daily one hour trigger 3/4 runs.
Swing:
     1) Production 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: 
     2) 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;

Shift Crew updates:
1) The Raster Coil pair Ax and Ay are off. Raster needs to be at 4x4.
2) Reduced the SHMS dipole LHE Lo alarm to 50 and LOLO alarm to 45.
3) 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.
4) With LNitrogen alarms are not that critical. Just need to start monitoring the problem with plot and halog the problem.
5) Of course any questions call the RC
