• Double-check the GuineaPig parameters that Anne used for the backscatter studies
    • Double-check the field maps from the anti-DID and the final focussing magnets
  • Double-check the Geant4 parameters that were used for those studies
  • EM showers: What dynamic range is required for the readout?
    • 500 GeV? 1000 GeV?
  • Cell size for EMCal?
  • Tracking performance (pt resolution) degraded from CDR to DBD
  • low-pt tracking performance shows some strange features
  • impact parameter resolution shows a charge-dependent bias 
  • forward region not optimized – two large clusters due to background in 1 TeV running
  • Tracker layout not optimized for air cooling (disks close off the barrel)
  • Tracker barrel aspect ratio not optimal. Barrel should be longer
  • KPIX buffer too small in forward region
  • Study of Neutron Flux (http://www.slac.stanford.edu/cgi-wrap/getdoc/slac-tn-07-013.pdf)
  • MAPS tracker – what's the advantage? --> Bristol

  • MAPS ECAL – is it better than the Analog ECAL?

  • No labels
