Contents
Preliminary Schedule
- 9/1 Installation and survey until ~18:00 (actually ended closer to ~21:00 followed by sweep)
- 9/2 00:00 - 9/2 10:00 -- Straight-track data (10 hours, Tuesday night)
- 9/2 10:00 - 9/2 20:00 -- Ramp solenoid magnet (8 hours, Wednesday day during RF recovery)
- 9/2 20:00 - 9/3 14:00 -- Full-field data: tracking mode (18 hours, Wednesday night)
- 9/3 14:00 - 9/3 20:00 -- Full-field data: TRD mode (4 hours, Thursday afternoon)
- 9/3 De-installation -- Technical crew de-install in the evening?
Notes:
- Assumes ~50% beam availability as normal. Schedule could be delayed if beam is down for prolonged period
- Magnet ramp on Tuesday morning begins at 10 am to coincide with RF recovery
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 (on amorphous ladder)
- 2 hours: focused FCAL trigger in GEM location (FCAL_TRACK_CENT.conf) to verify TRD/GEM signals (raw mode)
- Sergey will be available to setup and test GEM/TRD in DAQ with this configuration
- 8 hours: standard FCAL-BCAL trigger (FCAL_BCAL_PS_m9.conf) for alignment data
- Start new run every ~2 hours for calibration stability
- Monitor TRD histograms in RootSpy and typical occupancies (which will be different due to solenoid field being off)
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: diamond 0/90 PARA all using DAQ config hd_all.tsg_DIRC_TRD_HL
- 2 hours: focused FCAL trigger in GEM location at 150 nA (to verify TRD/GEM signals in raw mode)
- For focused trigger use CONFIG file FCAL_TRACK_CENT20_m9_TRDm10.conf
- 8 hours: standard FCAL_BCAL_PS_m9.conf trigger config at 150 nA (low energy TAGH turned on)
- Four 2-hour long runs with stable beam
- Turn off low energy TAGH counters using instructions at https://logbooks.jlab.org/entry/3830977: in TAGH HV GUI load configuration TAGH_HV_ProductionSummer2020_350nA.snap prior to increasing current above 150 nA
- 4 hours: standard FCAL_BCAL_PS_m9.conf trigger config at 250 nA (low energy TAGH turned off)
- Two 2-hour long runs with stable beam
- 4 hours: standard FCAL_BCAL_PS_m9.conf trigger config at 350 nA (low energy TAGH turned off)
- Two 2-hour long runs with stable beam
- 2 hours: focused FCAL trigger in GEM location at 150 nA (to verify TRD/GEM signals in raw mode)
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 are required for these runs)
- 4 hours: standard FCAL-BCAL trigger
Required personnel
- Expert in counting house or on-call for changes in configuration
