ExN02ChamberParameterisation.cc change

  • change number of chambers
 //NbOfChambers = 5;
 NbOfChambers = 1;
  • add new materials
 //Liquid Hydrogen
 G4Material* LH2=
 new G4Material("Hydrogen", z=1., a=1.01*g/mole, density = 0.07*g/cm3,
                kStateGas, 3*kelvin, 1.7e5*pascal);
 //BadVacuum
 density=universe_mean_density;
 temperature=0.1*kelvin;
 pressure=1.e-19*pascal;
 G4Material* BadVacuum=
 new G4Material("Galactic", z=1., a=1.01*g/mole, density,
                kStateGas, temperature, pressure);
  • define target as Liquid Hydrogen
 //TargetMater  = Pb;
 TargetMater  = LH2;
  • change LogicWorld to BadVacuum
 //logicWorld= new G4LogicalVolume( solidWorld, Air, "World", 0, 0, 0);
 logicWorld= new G4LogicalVolume( solidWorld, BadVacuum, "World", 0, 0, 0);
  • change LogicTracker to BadVacuum
 //logicTracker = new G4LogicalVolume(solidTracker , Air, "Tracker",0,0,0);  
 logicTracker = new G4LogicalVolume(solidTracker , BadVacuum, "Tracker",0,0,0);
