June 15th, 2015 (Evening Run)

Aim: Tracker timing, calibrating TOFs with tracker veto

Daily schedule

June 15th
Time 10pm - 6am
MOM V. Blackmore
Lead shifter A. Young
Shifter 2 F. Drielsma
BLOC C. Heidt
SOC C. Heidt
Experimenter E. Overton, M. Uchida
Physics Shifter C. Heidt
Beam? Yes
Additional Personnel

Shift plan:

  • 8:45pm
    • Shifters + BLOC arrive
    • Hall and beam line to be closed and prepared for beam
  • 10pm
    • Experimenters begin
    • E. Overton to add tracker veto to DAQ
    • Study tracker timing as in June 7th, Evening Run, triggering off TOF0
    • Study tracker timing when triggering off TOF1
    • Calibrate TOFs with tracker veto, aiming for 100k triggers per TOF.

Data Requested

  • TOF calibration

Beamline Configurations

  • We expect to run with 2V beamloss and the beam bump active.
  • DS is currently off
  • Beam settings via Run Control -- NB: "Calibration" button in Run Control does not (yet) set a TOF calibration beam.
    • TOF calibration, long 100k triggers run -- aim for 1000 triggers/pixel/tof (~25'000 spills, or until the end of the shift)

Initial Scans from Sundays Timing:

Note: Downstream tracker has timing interpolated from upstream. Its a Guess.

Tracker timing studies

  • Beam settings as dictated by E. Overton & M. Uchida
  • Reference run w/o DS, (6, 200) mu+ beam (number of triggers not yet specified)
  • Reference pion beam (number of triggers not yet specified)
