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¶
