void Config

(

)

Create the run configuration In constructor user has to specify the geometry input and select geometry navigation via the following options:

• geomVMCtoGeant4 - geometry defined via VMC, G4 native navigation
• geomVMCtoRoot - geometry defined via VMC, Root navigation
• geomRoot - geometry defined via Root, Root navigation
• geomRootToGeant4 - geometry defined via Root, G4 native navigation
• geomGeant4 - geometry defined via Geant4, G4 native navigation

The second argument in the constructor selects physics list:

• emStandard - standard em physics (default)
• emStandard+optical - standard em physics + optical physics
• XYZ - selected hadron physics list ( XYZ = LHEP, QGSP, ...)
• XYZ+optical - selected hadron physics list + optical physics

The third argument activates the special processes in the TG4SpecialPhysicsList, which implement VMC features:

• stepLimiter - step limiter (default)
• specialCuts - VMC cuts
• specialControls - VMC controls for activation/inactivation selected processes
• stackPopper - stackPopper process When more than one options are selected, they should be separated with '+' character: eg. stepLimit+specialCuts.

create the Specific stack

Customise Geant4 setting (verbose level, global range cut, ..)
