06/10/2008

  • Zach: Final stages of producing initial flight calibrations including crosstalk corrections, etc.
  • Fred: Working on L&EO timeline for calibration. Redoing ion rate plots layer by layer
  • Berrie: Berrie, David, Zach, Sasha working on adapting David's LAC calibration model for NomSciOps data - about done. Next is FLE
  • Elliott: Yvonne needs to redo energy deposit study vs angle, energy with new MC (including LPM, etc)

06/17/2008

  • Berrie points out that being able to "join" AFEE temps and other calibration information would be desirable. He will look into this @ SLAC
  • Fred will submit sims to Zach's requirement to SLAC or Lyon pipeline
  • Fred asks who is responsible for validating filter performance during L&EO? Fred will send a note to Richard Hughes and Eric Grove about this

06/24/2008

  • Simulations for proton/interrange testing
  • Status
    • Zach
      • knee deep in proton interrange calibration code
        • currently building new app utilizing existing Muon & GCR calib code
        • Took some work, but now we have appropriate simulation code - intend to run existing GCR calib code on the new sim.

  • NOTES
    • Berrie et. al. will do long term monitoring of threshold and LAC settings
    • Fred et. al. will do energy calibration monitoring using GCR
    • Suggestion that monitoring processes highlight new outliers
    • In GCR monitoring, we need to determine correct tradeoff between peak width (i.e. more stringent cuts) and statistics (less stringent cuts)
    • Sasha will be Zach's replacement as contact for threshold settings questions, deliveries, etc.
