June 18th, 2015 (Evening Run)

Aim: Downstream tracker debugging, if all OK beam through to downstream tracker

Daily schedule

June 18th
Time 10pm - 6am
MOM V. Blackmore
Lead shifter C. Heidt
Shifter 2 P. Francini
BLOC P. Hanlet
SOC C. Heidt
Experimenter E. Overton, M. Uchida
Physics Shifter C. Rogers
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
    • Debug downstream tracker using pion reference beam and TOF1 trigger
    • If downstream tracker deemed ready for data by experts:
      • If DS on: run (6, 200) muon beam through to EMR for remainder of shift
      • If DS off: TOF calibration

Data Requested

  • (6, 200) muon beam or TOF calibration

Beamline Configurations

  • We expect to run with 2V beamloss and the beam bump active.
  • DS status in flux
  • Beam settings via Run Control -- NB: "Calibration" button in Run Control does not (yet) set a TOF calibration beam.

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 pion beam (number of triggers not yet specified)

(6, 200) mu+ beam with DS
