Detailed Description

The Class for CDC Sensitive Detector.

In this class, every variable defined in CDCB4VHit will be calculated. And save CDCB4VHit into hits collection.

Member Function Documentation

◆ ProcessHits()

bool ProcessHits	(	G4Step *	aStep,
		G4TouchableHistory *	aROhist
	)

inlineprivatevirtualinherited

Check if recording hits is enabled and if so call step() and set the correct MCParticle flag.

Called by Geant4 for each step inside the sensitive volumes attached

Definition at line 94 of file SensitiveDetectorBase.h.

◆ registerMCParticleRelation() [1/2]

static void registerMCParticleRelation	(	const RelationArray &	relation,
		RelationArray::EConsolidationAction	ignoreAction = `RelationArray::c_negativeWeight`
	)

inlinestaticinherited

Overload to make it easer to register MCParticle relations.

Parameters

relation	RelationArray to register
ignoreAction

Definition at line 66 of file SensitiveDetectorBase.h.

◆ registerMCParticleRelation() [2/2]

void registerMCParticleRelation	(	const std::string &	name,
		RelationArray::EConsolidationAction	ignoreAction = `RelationArray::c_negativeWeight`
	)

staticinherited

Register an relation involving MCParticles.

All Relations which point from an MCParticle to something have to be registered with addMCParticleRelation() because the index of the MCParticles might change at the end of the event. During simulation, the TrackID should be used as index of the MCParticle

Parameters

name	Name of the relation to register
ignoreAction

Definition at line 22 of file SensitiveDetectorBase.cc.

◆ setActive()

static void setActive ( bool activeStatus )

inlinestaticinherited

Enable/Disable all Sensitive Detectors.

By default, all sensitive detectors won't create hits to make it possible to use the Geant4 Navigator for non-simulation purposes. Only during simulation the sensitive detectors will be enabled to record hits

Parameters

activeStatus bool to indicate wether hits should be recorded

Definition at line 50 of file SensitiveDetectorBase.h.

Member Data Documentation

◆ m_hitNumber

int m_hitNumber

private

The current number of created hits in an event.

Used to fill the DataStore CDC array.

Definition at line 277 of file CDCSensitiveDetector.h.

◆ m_hitWithPosWeight

std::multimap<unsigned short, CDCSimHit*> m_hitWithPosWeight

private

Map containing hits with positive weight.

Map may be replaced by vector, which may make the job speed faster... Try later.

Definition at line 280 of file CDCSensitiveDetector.h.

◆ m_minTrackLength

G4double m_minTrackLength

private

Min.

track length (mm) required for saving in MCParticle.

Definition at line 275 of file CDCSensitiveDetector.h.

◆ m_nonUniformField

G4int m_nonUniformField

private

Magnetic field is uniform or non-uniform.

0: uniform B field (1.5 T), 1: non-uniform B field.
