Constructor & Destructor Documentation

MyPrimaryGenerator()

MyPrimaryGenerator::MyPrimaryGenerator

(

)

Constructor of the class.

It defines the UI commands through DefineCommands() and gives default values to the settable variables. Then, it instantiates the G4ParticleGun object, representing the source of one primary gamma.

Definition at line 7 of file generator.cc.

Member Function Documentation

GeneratePrimaries()

void MyPrimaryGenerator::GeneratePrimaries ( G4Event *  anEvent )

override

It generates the primary vertex of the event.

In standard mode with spread disabled, a gamma particle is generated with energy randomly sampled from a Gaussian distribution with mean fMeanEnergy and stdev fSigmaEnergy, directed towards the center of the front face of the crystal perpendicular to it. If the spread is enabled, the gamma particle may be generated with incident angles that fall within the surface of the radius fRadiusSpread defined on the front face. In calibration mode, the isotropic emission of an optical photon from a monochromatic blue LED (GS::energyLED) situated in one of the light guide's cavities is simulated.

Parameters

anEvent

Pointer to the G4Event.
