CaTS and Dual ReadoutCaTS – Calorimeter and Tracker Simulation
  • http://home.fnal.gov/~wenzel/CaTS.html
  • Describe detector in gdml file (xml like)
  • Define sensitive detector types
  • TrackerSD(Hit)
  • CalorimeterSD(Hit)
  • DRCalorimeterSD(Hit) (Calorimeter + counts produced Cerenkov photons)
  • StoppingCalorimeterSD (kills particle after registering total energy)
  • PhotonSD(Hit): sensitive detector that registers optical photons.
  • CaTS - Output
  • uses Root reflexion (gccxml) to automatically create dictionaries for all Hit classes to make the Hits persistent and stores the result in a ROOT file.
  • Analysis Module allows output of more specific data that is not contained in the Hits class (generation process, particle types)
  • Hits Class contains SD Type, Location + detector specific data
  • Tiled Sampling Detector
  • 1.01m x 1.01m, 1 cm square tiles
  • 1.5 m total absorber width (brass)
  • Separate runs with different absorber
  • 25 mm, 50 mm and 75 mm per layer.
  • Total absorber kept constant.
  • Each layer detectors:
  • 7 mm quartz & 5 mm scintillator.
  • Count only Cerenkov photons and ionization
  • Procedure
  • Protons only at fixed energy.
  • Measure energy content, and size of the shower where Cherenkov is used to tag the energy deposition.
  • Measure resolution of shower with the reduced shower radius.

  • With Cherenkov tagging effective radius of shower is significantly reduced.
  • Move to actual HE configuration.
  • Study flow inside the calorimeter.
  • Overlapping particles.
