Preliminary Schedule
- 9/1 Installation and survey until ~18:00
- 9/1 18:00 - 9/2 04:00 -- Straight-track data (10 hours, Tuesday night)
- 9/2 04:00 - 9/2 12:00 -- Ramp solenoid magnet (8 hours, Wednesday day)
- 9/2 12:00 - 9/3 06:00 -- Full field data: tracking mode (18 hours, Wednesday night)
- 9/3 06:00 - 9/3 10:00 -- Full field data: TRD mode (4 hours, Thursday day)
- 9/3 De-installation -- Technical crew de-install in the afternoon?
Notes:
- Assumes ~50% beam availability as normal. Schedule could be delayed if beam is down for prolonged period
- Could do activities which don't require solenoid on Wednesday (9/2) morning while magnet is ramping
Calibration datasets
Summary page for Summer 2020 TRD/GEM Commissioning lists the relevant run ranges for the datasets collected below
Straight-track data
- For alignment of the GEM/TRD we need to acquire production samples with the magnetic field off
- Straight-track sample at the beam-center TRD positions with the full GEM readout for tracking and alignment studies
- Standard GlueX no-field measurements with 50nA on 10^-4 amorphous radiator
- 2 hours: focused FCAL trigger in GEM location to verify TRD/GEM signals (raw mode)
- 8 hours: standard FCAL-BCAL trigger for alignment data
Full-field data: tracking mode
- With the aligned GEM/TRD collect data for track extrapolation validation and multi-plane tracking directly upstream of DIRC
- Full solenoid field sample at the beam-center TRD positions with the full GEM readout for tracking and alignment studies
- Standard GlueX running conditions at 150nA, 250 nA and 350nA
- 2 hours: focused FCAL trigger in GEM location to verify TRD/GEM signals (raw mode)
- 8 hours: standard FCAL-BCAL trigger at 150 nA (low energy TAGH turned on)
- 4 hours: standard FCAL-BCAL trigger at 250 nA (low energy TAGH turned off)
- 4 hours: standard FCAL-BCAL trigger at 350 nA (low energy TAGH turned off)
Full-field data: TRD mode
- For pion rejection performance acquire samples with the TRD in "cluster counting" mode with all the GEM packages read out.
- Operate TRDs with two different gasses using raw mode (Lubomir and Sergey required)
- 4 hours: standard FCAL-BCAL trigger
