◆ ClearHitGroups()

void KVDetectionSimulator::ClearHitGroups ( )

inline

Reset any detectors/groups hit by previous detection

Definition at line 65 of file KVDetectionSimulator.h.

◆ DetectEvent()

void KVDetectionSimulator::DetectEvent	(	KVEvent *	event,
		const Char_t *	detection_frame = `""`
	)

Simulate detection of event by multidetector array.

optional argument detection_frame(="" by default) can be used to give name of inertial reference frame (defined for all particles of 'event') to be used. e.g. if the simulated event's default reference frame is the centre of mass frame, before calling this method you should create the 'laboratory' or 'detector' frame with KVEvent::SetFrame(...), and then give the name of the 'LAB' or 'DET' frame as 3rd argument here.

For each particle in the event we calculate first its energy loss in the target (if the target has been defined, see KVMultiDetArray::SetTarget). By default these energy losses are calculated from a point half-way along the beam-direction through the target (taking into account the orientation of the target), if you want random depths for each event call GetTarget()->SetRandomized() before using DetectEvent().

If the particle escapes the target then we look for the group in the array that it will hit. If there is one, then the detection of this particle by the different members of the group is simulated.

The detectors concerned have their fEloss members set to the energy lost by the particle when it crosses them.

Give tags to the simulated particles via KVNucleus::AddGroup() method Two general tags :

DETECTED : cross at least one active layer of one detector
UNDETECTED : go through dead zone or stopped in target We add also different sub group :
For UNDETECTED particles : "DEAD ZONE", "STOPPED IN TARGET" and "THRESHOLD", the last one concerned particle go through the first detection stage of the multidetector array but stopped in an absorber (ie an inactive layer)
For DETECTED particles : "PUNCH THROUGH" corrresponds to particle which cross all the materials in front of it (high energy particle punh through), or which miss some detectors due to a non perfect overlap between defined telescope, "INCOMPLETE" corresponds to particles which stopped in the first detection stage of the multidetector in a detector which can not give alone a clear identification,

Reset detectors in array hit by any previous events

Definition at line 64 of file KVDetectionSimulator.cpp.

◆ DetectParticle()

KVNameValueList KVDetectionSimulator::DetectParticle ( KVNucleus * part )

Simulate detection of a single particle

Propagate particle through the array, calculating its energy losses in all absorbers, and setting the energy loss members of the active detectors on the way.

Returns a list containing the name and energy loss of each detector hit in array (list is empty if none i.e. particle in beam pipe or dead zone of the multidetector)

Definition at line 197 of file KVDetectionSimulator.cpp.

◆ DetectParticleIn()

KVNameValueList KVDetectionSimulator::DetectParticleIn	(	const Char_t *	detname,
		KVNucleus *	kvp
	)

Given the name of a detector, simulate detection of a given particle by the complete corresponding group. The particle's theta and phi are set at random within the limits of detector entrance window

Returns a list containing the name and energy loss of each detector hit in array
