#* We continued discussing Simon's result from the last meeting where he used generated pion tracks truogh FDC only, tilted FDC (with less than 0.5mrd) and got features in the pulls vs phi. The question is with respect to what the tilt was done - in his case only the magnetic field was left with original coordinates. In Alex's case that was also w.r.t. the beam line as the kinfit was used. Alex and Eugene: the alignment procedure that Keigo is doing, will not give you the orientation of the whole tracking system w.r.t global coordinates. For that we need measurements with additional tracking detector(s) that are well surveyed.

  1. Run preparations
    • CDC
      • Beni did pedestal calibration and Naomi looked at the cosmic data taken last weekend; one f125 needs to be replaced. Naomi's plugin for monitoring the trigger word in f125 will be included at least in the plot browser, she is generating training samples so that Hydra can also watch it. The Primex experiment will start with no field and Naomi will not be able to calibrate the detector (or check that is is working properly) until the field is on.

      • FDC operates at nominal HV and is stable. However, running the DAQ with the FDC is not stable, at least two f125 need to be replaced, some noise appears on several cards that is not seen with a scope in front of the f125. Sergey suspects also issues with the firmware. Need to wait till Monday when Cody is back.
    • GEM-TRD
      • Testing setup that includes three TRDs has been install at the PS: one standard using GEMs and strip readout, another with large-pad readout, and a TRD with microMegas amplification.
  2. Tracking
    • We continued discussing Simon's result from the last meeting where he used generated pion tracks truogh FDC only, tilted FDC (with less than 0.5mrd) and got features in the pulls vs phi. The question is with respect to what the tilt was done - in his case only the magnetic field was left with original coordinates.
