0001 # Examples
0002 Here we provide examples for running CaTS (without Opticks). The examples consist of a gdml file to define the detector configuration.
0003
0004 ## homogeneous Crystal Calorimeter
0005 Here we just read out the energy deposited in a huge Crystal.
0006
0007     time ./CaTS -g homogeneous_pbwo_crystalcal.gdml  -pl 'FTFP_BERT'  -m pip_IO_Calo.mac
0008     time ./readCalorimeterHits CaloHits_Run0.root CaloHistos.root CalorimeterVolume
0009
0010 The created histogram can then be looked at using ROOT

0014 ## Dual Read out Crystal Calorimeter
0015
0016 Here in addtion to the deposited energy in the calorimeter cell we readout the number of Cerenkov photons that have been produced.
0017
0018     ./CaTS -g crystalcal_pbwo.gdml -pl 'FTFP_BERT+OPTICAL'  -m pip_IO_DR.mac
0019     ./readDRCalorimeterHits  DRCaloHits_Run0.root DRCaloHhstos.root CalorimeterVolume

0021 ## multiple scattering at a thin Diamond layer
0022
0023 In this example we register the momentum of a particle as it undergaos multiple scatering in a thin Diamond layer.
0024
0025     ./CaTS -g DiamondTarget.gdml -pl 'FTFP_BERT' -m msc.mac
0026     ./readMscHits  Msc_Run0.root ms_histos.root 'volTarget'
0027
0028
0029 The created histogram can then be looked at using ROOT
