June 16th, 2015 (Evening Run)¶

Aim: Upstream tracker debugging, if all OK beam through to upstream tracker

Daily schedule¶

June	16th
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. 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 upstream tracker using pion reference beam and TOF1 trigger
  • If upstream tracker deemed ready for data by experts: run (6, 200) muon beam through to upstream tracker for remainder of shift

Data Requested¶

• (6, 200) muon beam

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.

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)
