ExN02ChamberParameterisation.cc change

• change number of chambers

 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  = 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);
