Detailed Description

Base class for detector geometry description, interface to energy-loss calculations.

KVDetector is the base class for the description of all individual detectors in the KaliVeda framework. A detector is defined by the following characteristics:

it is composed of one or more absorber layers in which the energy loss of charged particles can be measured or calculated, described by KVMaterial objects;
it has a single active layer in which energy losses may be associated to data read out from some electronics/DAQ system via objects of the KVDetectorSignal class;
it can be attributed KVCalibrator objects used to transform raw KVDetectorSignal data into calibrated KVCalibratedSignal data;
it can have spacial dimensions and position (parent class KVPosition), when it is part of a KVMultiDetArray (array of detectors) deduced from a ROOT geometry description using class KVGeoImport:
- in this case, each KVDetector is associated with a node (KVGeoDetectorNode) in the geometry;
- each node is part of one or more trajectories (KVGeoDNTrajectory) which describe the possible flight paths of particles through the detectors of the array;
- the trajectories allow to describe the spacial relationships between the different detectors of the array ("in front", "behind"), from which $\Delta E-E$ telescopes (KVIDTelescope) can be deduced which group pairs of adjacent detectors along the trajectories;
- each detector is also the first node of a trajectory leading back towards the target (KVReconNucTrajectory) which is used in event reconstruction (KVEventReconstructor, KVGroupReconstructor) to determine the trajectory of reconstructed nuclei (KVReconstructedNucleus) starting from the detectors the furthest from the target which are fired in each event read from the raw data (KVRawDataReconstructor).

Example 1: defining a detector

KVDetector chio("Myl", 2.5*KVUnits::um);                       //first layer - 2.5 micron mylar window
KVMaterial *gas = new KVMaterial("C3F8", 5.*KVUnits::cm, 50.0*KVUnits::mbar);
chio.AddAbsorber(gas);                                         //second layer - 5cm of C3F8 gas at 50mbar pressure
chio.SetActiveLayer(gas);                                      //make gas layer "active"
KVMaterial *win = new KVMaterial("Myl",2.5*KVUnits::um);       //exit window
chio.AddAbsorber(win);

A detector is created either with the constructor taking the material type as argument:

KVDetector det("Si");

or using SetMaterial:

KVDetector det;

det.SetMaterial("Si");

KVDetector::SetMaterial

void SetMaterial(const Char_t *type) override

Definition: KVDetector.cpp:169

or it is created when a ROOT geometry is imported into a KVMultiDetArray object using KVGeoImport.

Calculate the energy loss of a charged particle in a detector

Two methods are available: one simply calculates the energy lost by the particle in the detector, but does not modify either the particle or the detector (GetELostByParticle); the other simulates the passage of the particle through the detector, the particle's energy is reduced by the amount lost in the detector's absorbers and the total energy lost in the detector is increased, e.g.:

KVNucleus alpha(2,4);           //an alpha-particle
alpha.SetEnergy(100);           //with 100MeV kinetic energy
det.DetectParticle(&alpha);     //simulate passage of particle in the detector/target
det.GetEnergy();                        //energy lost by particle in detector/target
alpha.GetEnergy();                      //residual energy of particle
det.Clear();                            //reset detector ready for a new detection
 
KVNucleus xe("129Xe", 50.0);   // 50 MeV/nucleon 129Xe ion
 
chio.DetectParticle(&xe);
 
chio.GetEnergyLoss()
(double) 48.309654        // energy loss in gas (active) layer
 
xe.GetEnergy()
(double) 6380.9388       // kinetic energy of 129Xe after detector
 
50*129 - xe.GetEnergy() - chio.GetEnergyLoss()
(double) 20.751563       // energy lost in Mylar windows
 
chio.GetIncidentEnergy(54,129,chio.GetEnergyLoss())
(double) 6450.0000 // deduce incident energy from dE - corrected for Mylar
 
chio.GetIncidentEnergyFromERes(54,129,xe.GetEnergy())
(double) 6450.0000 // deduce incident energy from Eres - corrected for Mylar

Important note on detector positions, angles, solid angle, distances etc.

For detector geometries based on the ROOT geometry package, the following methods refer to the surface of the first volume constituting the detector crossed from the target (referred to as the "entrance window"):

void GetRandomAngles();

TVector3 GetCentreOfEntranceWindow() const;
Double_t GetTheta() const;
Double_t GetSinTheta() const;
Double_t GetCosTheta() const;
Double_t GetPhi();

Double_t GetSolidAngle(void);

◆ FindZmin()

Int_t KVDetector::FindZmin	(	Double_t	ELOSS = `-1.`,
		Char_t	mass_formula = `-1`
	)

virtual

For particles which stop in the first stage of an identification telescope, we can at least estimate a minimum Z value based on the energy lost in this detector.

This is based on the KVMaterial::GetMaxDeltaE method, giving the maximum energy loss in the active layer of the detector for a given nucleus (A,Z).

The "Zmin" is the Z of the particle which gives a maximum energy loss just greater than that measured in the detector. Particles with Z<Zmin could not lose as much energy and so are excluded.

If ELOSS is not given, we use the current value of GetEnergy() Use 'mass_formula' to change the formula used to calculate the A of the nucleus from its Z. Default is valley of stability value. (see KVNucleus::GetAFromZ).

If the value of ELOSS or GetEnergy() is <=0 we return Zmin=0

Definition at line 850 of file KVDetector.cpp.

◆ Fired()

virtual Bool_t KVDetector::Fired ( Option_t * opt = "any" ) const

inlinevirtual

Returns kTRUE if detector was hit (fired) in an event

The actual meaning of hit/fired depends on the context and the option string opt.

If the detector is in "simulation mode", i.e. if SetSimMode(kTRUE) has been called, this method returns kTRUE if the calculated energy loss in the active layer is > 0.

In "experimental mode" (i.e. IsSimMode() returns kFALSE), depending on the option:

opt="any" (default): Returns true if ANY of the raw parameters associated with the detector were present in the last handled event opt="all" : Returns true if ALL of the raw parameters associated with the detector were present in the last handled event

◆ GetCorrectedEnergy()

virtual

Returns the total energy loss in the detector for a given nucleus including inactive absorber layers. e = energy loss in active layer (if not given, we use current value) transmission = kTRUE (default): the particle is assumed to emerge with a non-zero residual energy Eres after the detector. = kFALSE: the particle is assumed to stop in the detector.

WARNING: if transmission=kTRUE, and if the residual energy after the detector is known (i.e. measured in a detector placed after this one), you should first call SetEResAfterDetector(Eres); before calling this method. Otherwise, especially for heavy ions, the correction may be false for particles which are just above the punch-through energy.

WARNING 2: if measured energy loss in detector active layer is greater than maximum possible theoretical value for given nucleus' Z & A, this may be because the A was not measured but calculated from Z and hence could be false, or perhaps there was an (undetected) pile-up of two or more particles in the detector. In this case we return the corrected energy corresponding to the maximum theoretical energy loss in the active layer and we add the following parameters to the particle (in nuc->GetParameters()):

GetCorrectedEnergy.Warning = 1 GetCorrectedEnergy.Detector = [name] GetCorrectedEnergy.MeasuredDE = [value] GetCorrectedEnergy.MaxDE = [value] GetCorrectedEnergy.Transmission = 0 or 1 GetCorrectedEnergy.ERES = [value]

overridevirtual

Overrides KVMaterial::GetIncidentEnergy Returns incident energy corresponding to energy loss delta_e in active layer of detector for a given nucleus. If delta_e is not given, the current energy loss in the active layer is used.

By default the solution corresponding to the highest incident energy is returned This is the solution found for Einc greater than the maximum of the dE(Einc) curve. If you want the low energy solution set SolType = KVIonRangeTable::kEmin.

WARNING: calculating the incident energy of a particle using only the dE in a detector is ambiguous, as in general (and especially for very heavy ions) the maximum of the dE curve occurs for Einc greater than the punch-through energy, therefore it is not always true to assume that if the particle does not stop in the detector the required solution is that for type=KVIonRangeTable::kEmax. For a range of energies between punch-through and dE_max, the required solution is still that for type=KVIonRangeTable::kEmin. If the residual energy of the particle is unknown, there is no way to know which is the correct solution.

WARNING 2 If the given energy loss in the active layer is greater than the maximum theoretical dE for given Z & A, (dE > GetMaxDeltaE(Z,A)) then we return a NEGATIVE incident energy corresponding to the maximum, GetEIncOfMaxDeltaE(Z,A)
