// 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
|
||||
// distributions. It is used by the General Particle source class
|
||||
// and it is derived from G4VPrimaryGenerator.
|
||||
//
|
||||
// Note on thread safety:
|
||||
// G4SingleParticleSource instances can be shared among threads. GeneratePrimaryVertex
|
||||
// is protected via a mutex because underlying generators are not assumed to be thread-safe.
|
||||
// Note that internal status of this class is assumed to be changed by master thread (typically
|
||||
// via UI commands).
