Revision as of 17:09, 14 December 2019

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: [1]
- Beam CENTER: Runs 70757-70786 taken with FCAL_TRACK_CENT configuration

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.
