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)
