Current Status

  • Steady beam and data taking so far over the weekend
  • Q2=3.85 W=2.62 x=0.39 low epsilon LD2+ central setting done
  • Q2=3.85 W=2.62 x=0.39 low epsilon LD2+ left setting - 6k pions (reduced from 10k goal)
  • Q2=3.85 W=2.62 x=0.39 low epsilon LH2+ left setting - 6k pions (reduced from 10k goal)

Current Run Plan

  • Finish off the Q2=3.85 W=2.62 x=0.39 low epsilon LH2+ central setting
    • ~5k pions as of 11:00 on 21/8/22
    • 10k target (~7-8 hours of good beam left to reach this)
  • Go back to the Q2=3.85 W=2.62 x=0.39 low epsilon LH2+ left setting
    • Get 2k more pions here (~4 hours)
  • Q2=3.85 W=2.62 x=0.39 low epsilon LD2+ left setting after this if time permits
    • Need another 2k pions here (~4 hours again)

Notices in Effect for Shift Crew

  • If all SHMS magnets crash at the same time, push the SHMS dipole crash button (on the rack above the target heater manual controls and target temperature readbacks).
  • For physics settings that come in quickly, please see - Analysis Note #1 Analysis Note #2
  • Please see updated CoVID guidance for the weekend - Weekend CoVID Guidance
  • Consult current issues posts below carefully
    • Check for any indication that the collimator has moved in the 50k replays
    • Check DC/Calorimeter plots in the 50k carefully

Current Issues

Planned Accesses to the Hall

  • SHMS rotation to 5.50 on Monday (22/8) morning
    • Beam off and call for survey at 08:00

Special Requests

  • Fix coffee machine, or replace.
  • BCM Calibration - Tuesday (23/8)?
    • Dave M is going to provide an updated procedure.
  • Beam energy measurement - Tuesday/Wednesday?
