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: Available options: EMonly, EMonly+Extra, Hadron_EM, Hadron_EM+Extra where EMonly = emStandard Hadron = FTFP_BERT FTFP_BERT_TRV FTFP_BERT_HP FTFP_INCLXX FTFP_INCLXX_HP FTF_BIC LBE QBBC QGSP_BERT QGSP_BERT_HP QGSP_BIC QGSP_BIC_HP QGSP_FTFP_BERT QGSP_INCLXX QGSP_INCLXX_HP QGS_BIC Shielding ShieldingLEND EM = _EMV _EMX _EMY _EMZ _LIV _PEN Extra = extra optical radDecay The Extra selections are cumulative, while Hadron selections are exlusive.

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 G4 VMC

create the Specific stack

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