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.
