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)
