Update on GSI Reanalysis (Eric N.)

  • See Eric's presentation here
  • No one understands (a priori) why multiplicity varies so dramatically between run 46 and run 186. Move investigation will be done

    Beamtest CAL calibration discussion (Benoit)

  • See Benoit's presentation on current calibration plans here
  • We want to make sure that xtal scanning plan for calibration samples all different xtal behaviors (e.g. different asymmetry curve shapes)
  • We may want to add beam positions nearer to xtal ends to investigate direct deposition in diodes
  • General consensus that beam position needs to be known for absolute (not relative) calibration. TKR can be used for 2 modules. What do we do for the other 2? Is CAL hodoscope direction good enough?

    GCR calibration flow chart comments

  • Benoit – Where do simulations enter in to the process?
    • Simulations are necessary to model asymm. shape of ion energy peaks (due to distribution of incident energies)
  • No labels
