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

Gakujyutsu Sousei Monthly Meeting

comparison of momentum resolution
Comparison of Momentum Resolution



  • 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.

LDC ( Tesla TDR )

SiD promissed better pictures

By the end of Oct.

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
    • Describe what is PFA
    • Typical PFA algorithm(s)
    • Typical PFA performance at Z pole and higher energy
      • Resolution : 90% RMS
      • SiD result ?
      • LDC – 30%/sqrt(E) at Z pole, but not good for ttbar, 500GeV
      • GLD – 30%/sqrt(E) at Z pole, barrel region
        • Not good in endcap region  Hope to improve soon
        • Still tile geometry.  Strip geometry ?
        • High Energy performance not good.  Hope : good for baseline physics

  • Particle ID\'s in jets (PFA)
    • Good PFA includes efficient and pure ID of g, e, m
    • Typical particle ID efficiency/purity shall (should ) be described.
    • What studies should be described and How ?
