Xebra_G4

Generic Geant4 Monte Carlo for XEBRA simulation:

• Overall G4 Structure and Physics List is based on the XENONnT Neutron Background simulation by D. Ramirez (Feb 2018)
• Detector Geometry contains a generic model of XEBRA (as of Nov 2018) by UniFr
• Cleaned up from traces of Geant4 versions <10 (code tested with G4 10.3.3.) and debugged w.r.t. G4SystemOfUnits and naming conventions (except for variables in detector construction)

Instructions for git:

• git clone [-b "BRANCH_NAME"] https://github.com/AG-Schumann/Xebra_G4.git
• cd Xebra_G4
• git checkout -b "BRACH_NAME"
• rsync -avP ../DIR_WITH_UPDATE/include/ include/
• rsync -avP ../DIR_WITH_UPDATE/src/ src/
• git add .
• git commit -m "ADD SOME COMMENT "
• git push origin "BRACH_NAME"

Compilation & Running Macros:

• make clean && make //compiling
• bin/Linux-g++/xebra_G4 -p macros/preinit.mac -f macros/run_geantino_all.mac -n 10000 //running the preinit + process macros --> output in root file ("event.root", unless specified differently).

Simple online root visualization:

• TFile *pFile = new TFile(inputfile+".root");
• TDirectoryFile *pDir = (TDirectoryFile *) pFile->Get("events");
• TTree *pTree = (TTree *) pDir->Get("events");
• pTree6->Draw("xp_pri:yp_pri:zp_pri");
