Examples

Here we provide examples for running CaTS (without Opticks). The examples consist of a gdml file to define the detector configuration.

homogeneous Crystal Calorimeter

Here we just read out the energy deposited in a huge Crystal.

time ./CaTS -g homogeneous_pbwo_crystalcal.gdml  -pl 'FTFP_BERT'  -m pip_IO_Calo.mac
time ./readCalorimeterHits CaloHits_Run0.root CaloHistos.root CalorimeterVolume

The created histogram can then be looked at using ROOT

Dual Read out Crystal Calorimeter

Here in addtion to the deposited energy in the calorimeter cell we readout the number of Cerenkov photons that have been produced.

./CaTS -g crystalcal_pbwo.gdml -pl 'FTFP_BERT+OPTICAL'  -m pip_IO_DR.mac 
./readDRCalorimeterHits  DRCaloHits_Run0.root DRCaloHhstos.root CalorimeterVolume

multiple scattering at a thin Diamond layer

In this example we register the momentum of a particle as it undergaos multiple scatering in a thin Diamond layer.

./CaTS -g DiamondTarget.gdml -pl 'FTFP_BERT' -m msc.mac
./readMscHits  Msc_Run0.root ms_histos.root 'volTarget'

The created histogram can then be looked at using ROOT
