1 // Modified for LArG4 by Ben Jones, MIT, Nov 2012
2 //
3 // Thisclass is based upon thedefaultGeant4 optical physics constructor.
4 // However, forfast optical physics inLArSoft:
5 //
6 // - The default geant4 scintillation process is swapped for the LArG4 fast
7 // scintillation process
8 //
9 // - Cerenkov light (still slow) can beenabledor disabled as required
10 //
11 // - The default geant4reflection process is swapped for a simpler
12 // custom boundary process in LArG4
13 //
14 // Parameters relating to the physics in this constructor can be set
15 // in the Utilities/LArParameters service.
