|
|
// --------------
|
|
//
|
|
// Version 1.0, 05/02/2004, Fan Lei, Created.
|
|
// Based on the G4GeneralParticleSource class in Geant4 v6.0

///////////////////////////////////////////////////////////////////////////////
|
|
//
|
|
// Class Description:
|
|
//
|
|
// The Single Particle Source is designed to extend the functionality of the
|
|
// G4ParticleGun class. It is designed to allow specification of input
|
|
// particles in terms of position, direction (or angular) and energy
|
|
// distributions. It is used by the General Particle source class
|
|
// and it is derived from G4VPrimaryGenerator.
|
|
