This class records tracking information at each step of a particle inside the simulation. It extracts position, momentum, deposited energy and other metadata (volume, process, etc.) for later analysis.

It also handles quadrupole-related information and collimator updates.

Constructor & Destructor Documentation

PlasmaMLPALLASSteppingAction()

PlasmaMLPALLASSteppingAction::PlasmaMLPALLASSteppingAction

(

)

Constructor.

Initializes the stepping action and messenger.

Initializes the Geant4 generic messenger and declares user commands for controlling tracking status (global and for collimators).

~PlasmaMLPALLASSteppingAction()

PlasmaMLPALLASSteppingAction::~PlasmaMLPALLASSteppingAction ( )

override

Destructor.

Cleans up the allocated messenger.

Member Function Documentation

SetInputInformations()

void PlasmaMLPALLASSteppingAction::SetInputInformations

(

PlasmaMLPALLASEventAction *

evtac

)

const

Store the initial particle information at the beginning of an event.

Store the initial beam parameters at the beginning of the event.

Parameters

evtac	Pointer to the event action where data will be stored.
evtac	Pointer to the event action where the values are stored.

SetQuadrupoleInformation()

void PlasmaMLPALLASSteppingAction::SetQuadrupoleInformation	(	PlasmaMLPALLASEventAction *	evtac,
		QuadID	quad,
		PositionType	posType
	)		const

Store quadrupole crossing information.

Store quadrupole-related information in the event statistics.

Parameters

evtac	Pointer to the event action.
quad	Identifier of the quadrupole.
posType	Position type (pre-step or post-step).
evtac	Pointer to the event action.
quad	Identifier of the quadrupole.
posType	Position type (begin or end of quadrupole).

UserSteppingAction()

void PlasmaMLPALLASSteppingAction::UserSteppingAction ( const G4Step *  aStep )

override

Stepping action executed at each Geant4 step.

Main Geant4 stepping action executed at each simulation step.

Extracts step information (positions, momenta, energy deposition, etc.) and stores it for later analysis. Also manages collimator updates.

Parameters

step	Current Geant4 step.

Collects track and step information (positions, momenta, energies, volumes). Manages input beam initialization, quadrupole crossing, collimator detection, YAG screens, and particle termination.

Parameters

aStep

Pointer to the current Geant4 step.
