Propagate particles through array geometry calculating energy losses.

Given a valid ROOT geometry, we propagate the particles of an event and, every time a particle traverses a volume made of a TGeoMaterial with a name corresponding to a material known by this range table, we calculate the energy loss of the particle, and store it in the particle's list of parameters in the form

"DE:[detector name]" = [energy lost in volume]

static Double_t energy[]

Definition: KVedaLossRangeFitter.cpp:17

In the case of multilayer detectors, [detector name] is replaced by [detector name]/[layer name].

Example of use

In this case the geometry is made up of 3-layer Ionisation Chamber detectors (window + gas + window), with an ACTIVE gas layer, and single-layer Silicon detectors placed behind the IC.

KVEvent* evt = new KVEvent();
KVNucleus* nuc = evt->AddParticle();
Double_t theta = gRandom->Uniform(0,30);
Double_t phi = gRandom->Uniform(0,360);
nuc->SetZAandE(1,1,200); nuc->SetTheta(theta); nuc->SetPhi(phi);
 
KVRangeTableGeoNavigator rtgn(gGeoManager, KVMaterial::GetRangeTable())
rtgn.PropagateEvent(evt);
evt->Print();

◆ ParticleEntersNewVolume()

void KVRangeTableGeoNavigator::ParticleEntersNewVolume ( KVNucleus * part )

virtual

Overrides method in KVGeoNavigator base class. Every time a particle enters a new volume, we check the material to see if it is known (i.e. contained in the range table fRangeTable). If so, then we calculate the energy loss of the particle in this volume, reduce the particle's energy accordingly, and, if the energy falls below a certain cut-off (default 1.e-3 MeV; can be modified with SetCutOffKEForPropagation(Double_t) ), we stop the propagation.

The (cumulated) energy losses in the active layers of all hit detectors are updated with the energy lost by this particle
