This class controls the generation of primary particles in the Geant4 simulation.
It integrates ONNX inference for beam parameter prediction and provides methods to configure laser and beam properties in a multithreaded environment.

Constructor & Destructor Documentation

PlasmaMLPALLASPrimaryGeneratorAction()

PlasmaMLPALLASPrimaryGeneratorAction::PlasmaMLPALLASPrimaryGeneratorAction	(	size_t	N,
		size_t	numThreads,
		bool	pMT
	)

Constructor.

Constructor for the primary generator action.

Parameters

N	Number of events to generate.
numThreads	Number of threads in multithreaded mode.
pMT	Flag to enable multithreading.

Initializes the particle gun, particle source, ONNX inference engine, and the associated UI messenger.

Parameters

N	Total number of events to generate.
numThreads	Number of threads used for multithreaded execution.
pMT	Flag indicating whether multithreading is enabled.

~PlasmaMLPALLASPrimaryGeneratorAction()

PlasmaMLPALLASPrimaryGeneratorAction::~PlasmaMLPALLASPrimaryGeneratorAction

(

)

Destructor.

Cleans up allocated resources such as the particle gun and particle source.

Member Function Documentation

GeneratePrimaries()

void PlasmaMLPALLASPrimaryGeneratorAction::GeneratePrimaries ( G4Event *  anEvent )

override

Generate primary particles for the event.

Generate primary particles for a simulation event.

Parameters

anEvent

Pointer to the current G4Event.

Depending on the ONNX status, this function either:

• Uses the ONNX model inference to generate beam parameters and configure the particle gun.
• Uses the Geant4 GeneralParticleSource (GPS) to generate the particle.

Parameters

anEvent

Pointer to the Geant4 event where primary particles are generated.
