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

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

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 [2] [3], and lost data [4]
    • Beam LEFT: Runs 71013-????? taken with FCAL_TRACK_LEFT configuration
      • Logbook entries: Argon gas [5] and TRD runs with Xenon gas ?????

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.
