Base class describing materials.

Important note about units

Since v6-17-02 the geometry package adopted a system of units, upon the request to support an in-memory material representation consistent with the one in Geant4. The adoption was done gradually and starting with v6-19-02 (back-ported to v6-18-02) the package supports changing the default units to either ROOT (CGS) or Geant4 ones. In the same version the Geant4 units were set to be the default ones, changing the previous behavior and making material properties such as radiation and interaction lengths having in memory values an order of magnitude lower. This behavior affected versions up to v6-25-01, after which the default units were restored to be the ROOT ones.

For users needing to restore the CGS behavior for material properties, the following sequence needs to be called before creating the TGeoManager instance: From v6-18-02 to v6-22-06:

TGeoUnit::setUnitType(TGeoUnit::kTGeoUnits);

From v6-22-08 to v6-25-01:

TGeoManager::LockDefaultUnits(false);
TGeoManager::SetDefaultUnits(kRootUnits);
TGeoManager::LockDefaultUnits(true);

◆ FillMaterialEvolution()

void TGeoMaterial::FillMaterialEvolution	(	TObjArray *	population,

virtual

Fills a user array with all the elements deriving from the possible decay of the top element composing the mixture.

Each element contained by <population> may be a radionuclide having a Bateman solution attached. The precision represent the minimum cumulative branching ratio for which decay products are still taken into account. To visualize the time evolution of each decay product one can use:

TGeoElement *elem = population->At(index);
TGeoElementRN *elemrn = 0;
if (elem->IsRadioNuclide()) elemrn = (TGeoElementRN*)elem;

One can get Ni/N1(t=0) at any moment of time. Ni is the number of atoms of one of the decay products, N1(0) is the number of atoms of the top element at t=0.

Double_t fraction_weight = elemrn->Ratio()->Concentration(time);

Find concentration of the element at a given time.
