Gakujyutsu Sousei Monthly Meeting

sub detector performance
Sub-Detector Performance
  • Philosophy
    • Pickup typical results from concept studies in order to show that detector performance used in the physics chapter is confirmed with some extent by full simulations.
  • Basics
    • Material budget of detectors
  • Tracker performacne
    • Momentum resolution: TPC (GLD, LDC, 4th), SiD
    • Track reconstruction
      • TPC: Old Tesla TDR result
      • SiD: VTX based, ECAL Based + SiD standalone

comparison of momentum resolution
Comparison of Momentum Resolution

GLD

LDC

  • GLD vs LDC
  • Difference in Low Pt region ?Is it by IT matterial ?
  • High Pt: TPC only resol. Different.
  • Spatial resolution difference ?
  • With VTX/IT Constraint, similar performance.
  • No CosTheta dep. From GLD.

SiD

calorimeter and pfa performance
Calorimeter and PFA Performance
  • Calorimeter performance for single particle
    • g/electron energy resolution & angular resolution
    • Pi+/Kaon_L energy resolution & angular resolution
  • PFA issues
