Summer 2020 TRD/GEM Commissioning

General logbook entries:

• Lubomir's status on 9/1/2020: [1]

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 center position with the full GEM readout for tracking and alignment studies
• Runs 72988 - 72992 taken with FCAL_TRACK_CENT20_m9_TRDm10 configuration
• Runs 72993-72995 taken with FCAL_BCAL_PS_m9 configuration
  • Logbook entries: initial correlations and comparison with tracks after mapping fix

Full GEM readout: tracking mode

• At least one large dataset will be required with the full readout for tracking and alignment studies with the full solenoid field
• Runs 73011-73013 taken with FCAL_TRACK_CENT20_m9_TRDm10 configuration, old focused trigger
• Runs 73027-73032 taken with FCAL_TRACK_CENT20_m9_TRDm10 configuration, new focused trigger for TRD studies (xenon gas?)

Runs taken with standard FCAL_BCAL_PS_m9 configuration

• 150 nA: Runs 73014-73018
• 250 nA: Runs 73020, 73033
• 350 nA: Runs 73034-73035
