		Int_t	A,
		Double_t	dE = `-1.0`,
		enum SolType	type = `kEmax`
	)

virtual

Calculate residual kinetic energy Eres (MeV) after the absorber from energy loss in absorber for nucleus (Z,A). If dE is not given, the energy loss in this absorber is used. For a KVDetector, dE = energy loss in the ACTIVE layer, not the total energy lost in crossing the detector (i.e. the incident energy of the particle is NOT given by dE + Eres: due to losses in the inactive layers of the detector, Einc > dE + Eres).

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 (i.e. below Bragg peak for gas detector) set SolType = KVMaterial::kEmin.

If the given energy loss in the absorber is greater than the maximum theoretical dE (dE > GetBraggDE) then we return the residual energy corresponding to the maximum dE.

Definition at line 750 of file KVMaterial.cpp.

◆ GetGeoMedium()

TGeoMedium * KVMaterial::GetGeoMedium ( const Char_t * med_name = "" )

virtual

By default, return pointer to TGeoMedium corresponding to this KVMaterial. If argument "med_name" is given and corresponds to the name of an already existing medium, we return a pointer to this medium, or 0x0 if it does not exist. med_name = "Vacuum" is a special case: if the "Vacuum" does not exist, we create it.

Instance of geometry manager class TGeoManager must be created before calling this method, otherwise 0x0 will be returned. If the required TGeoMedium is not already available in the TGeoManager, we create a new TGeoMedium corresponding to the properties of this KVMaterial. The name of the TGeoMedium (and associated TGeoMaterial) is the name of the KVMaterial.

Definition at line 971 of file KVMaterial.cpp.

◆ GetIncidentEnergy()

Double_t KVMaterial::GetIncidentEnergy	(	Int_t	Z,
		Int_t	A,
		Double_t	delta_e = `-1.0`,
		enum SolType	type = `kEmax`
	)

virtual

Calculate incident energy of nucleus (Z,A) corresponding to the energy loss in this absorber. If delta_e is not given, the energy loss in this absorber 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.

If the given energy loss in the absorber is greater than the maximum theoretical dE (dE > GetMaxDeltaE(Z,A)) then we return the incident energy corresponding to the maximum, GetEIncOfMaxDeltaE(Z,A)

Reimplemented in KVDetector.

Definition at line 788 of file KVMaterial.cpp.

	)

virtual

The maximum energy loss of this particle (corresponding to incident energy GetEIncOfMaxDeltaE(Z,A)) For detectors, this is the maximum energy loss in the active layer.

Reimplemented in KVDetector.

Definition at line 943 of file KVMaterial.cpp.

◆ GetParticleEIncFromERes()

Double_t KVMaterial::GetParticleEIncFromERes	(	KVNucleus *	kvn,

virtual

Calculate the energy of particle 'kvn' before its passage through the absorber, based on the current kinetic energy, Z & A of nucleus 'kvn'.

Returns the linear thickness of the material in cm. Use Units to change units: mat.GetThickness()/KVUnitsum ; in microns

Reimplemented in KVTarget, and KVSilicon.

Definition at line 380 of file KVMaterial.cpp.

◆ GetZ()

Double_t KVMaterial::GetZ ( ) const

Returns atomic number of material.

Definition at line 320 of file KVMaterial.cpp.

◆ init()

void KVMaterial::init ( void )

Default initialisations. No properties are set for the material (except standard temperature (19°C) and pressure (1 atm)) Default range table is generated if not already done. By default it is the VEDALOSS table implemented in KVedaLoss. You can change this by changing the value of environment variable KVMaterial.IonRangeTable.

Definition at line 45 of file KVMaterial.cpp.

◆ IsGas()

Bool_t KVMaterial::IsGas ( ) const

Returns kTRUE for gaseous materials/detectors.

Definition at line 305 of file KVMaterial.cpp.

◆ IsIsotopic()

Bool_t KVMaterial::IsIsotopic ( ) const

Returns kTRUE if a specific isotope has been chosen for the material using SetMass(). e.g. for "119Sn" this method returns kTRUE e.g. for "natSn" this method returns kFALSE

Definition at line 269 of file KVMaterial.cpp.

◆ IsNat()

Bool_t KVMaterial::IsNat ( ) const

Returns kFALSE if a specific isotope has been chosen for the material using SetMass(). e.g. for "119Sn" this method returns kFALSE e.g. for "natSn" this method returns kTRUE

Definition at line 288 of file KVMaterial.cpp.

◆ Print()

void KVMaterial::Print ( Option_t * option = "" ) const

virtual

Show information on this material.

Reimplemented from KVBase.

Reimplemented in KVDetector, KVCsI, and KVTarget.

Definition at line 571 of file KVMaterial.cpp.

◆ SetAbsGeoVolume()

virtual void KVMaterial::SetAbsGeoVolume ( TGeoVolume * v )

inlinevirtual

Definition at line 142 of file KVMaterial.h.

◆ SetAreaDensity()

void KVMaterial::SetAreaDensity ( Double_t dens )

Set area density in g/cm**2.

For solids, area density can only changed by changing linear dimension (fixed density). For gases, the density depends on temperature and pressure. This method leaves temperature and pressure unchanged, therefore for gases also this method will effectively modify the linear dimension of the gas cell.

Definition at line 406 of file KVMaterial.cpp.

◆ SetEnergyLoss()

virtual void KVMaterial::SetEnergyLoss ( Double_t e ) const

inlinevirtual

Reimplemented in KVDetector.

Definition at line 95 of file KVMaterial.h.

◆ SetMass()

void KVMaterial::SetMass ( Double_t a )

Set the atomic mass of the material - use if you want to change the default naturally occuring mass for some rarer isotope.

Definition at line 235 of file KVMaterial.cpp.

◆ SetMaterial()

void KVMaterial::SetMaterial ( const Char_t * mat_type )

virtual

Intialise material of a given type. The material must exist in the currently used range tables (fIonRangeTable). For materials which are elements of the periodic table you can specify the isotope such as "64Ni", "13C", "natSn", etc. etc.

Reimplemented in KVTarget, and KVDetector.

Definition at line 191 of file KVMaterial.cpp.

◆ SetPressure()

void KVMaterial::SetPressure ( Double_t p )

virtual

Set the pressure of a gaseous material (in torr) As this changes the density of the gas, it also changes the area density of the absorber (for fixed linear dimension)

Reimplemented in KVChIo.

Definition at line 443 of file KVMaterial.cpp.

◆ SetTemperature()

void KVMaterial::SetTemperature ( Double_t t )

virtual

Set temperature of material. The units are: degrees celsius As this changes the density of the gas, it also changes the area density of the absorber (for fixed linear dimension)

Definition at line 489 of file KVMaterial.cpp.

◆ SetThickness()

void KVMaterial::SetThickness ( Double_t t )

virtual

Set the linear thickness of the material in cm or use one of the Units constants: SetThickness( 30.*KVUnitsum ); set thickness to 30 microns

Reimplemented in KVDetector, KVSilicon, and KVINDRADetector.

Definition at line 354 of file KVMaterial.cpp.
