Fall 2019 TRD/GEM Commissioning

General logbook entries:

• Need to add pictures of installation and alignment...
• FCAL trigger configuration
• Lubomir's status on 12/5/19: before access and after access
• Drift voltage on wire TRD turned off on 12/12/19: [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 each of the 3 TRD positions with the full GEM readout for tracking and alignment studies
  • Beam LEFT: Runs 70703-70721 taken with FCAL_TRACK_LEFT configuration
  • Beam RIGHT: Runs 70728-70751 taken with FCAL_TRACK_RIGHT configuration
    • Logbook entries: [2]
  • Beam CENTER: Runs 70757-70786 taken with FCAL_TRACK_CENT configuration

Full GEM readout: tracking mode

• The electronics for three of the GEM packages are readout limited to ~3kHz
• At least one large dataset at each of the 3 TRD positions will be required with the full readout for tracking and alignment studies with the full solenoid field
  • Beam CENTER: Runs 70951-70992 taken with FCAL_TRACK_CENTER configuration
    • Logbook entries: Good runs [3] [4], and lost data [5]
  • Beam LEFT: Runs 71013-71026 and 71065-71069 taken with FCAL_TRACK_LEFT configuration
    • Logbook entries: Argon gas [6] and TRD runs with Xenon gas [7]
  • Beam RIGHT: Runs 71080-71102 and 71159-71160 taken with FCAL_TRACK_RIGHT configuration

Note: Data from Runs 70850-70895 were lost due to data transfer mistake. So although they may have events listed in RCDB, the data are not available.
