First of all, the aim of my code is to model a fission chamber using enriched uranium. To check if I use the apropriate physical processes, I model a plaque made of uranium and fire thermal neutron on it.
When I use the G4NeutronHPorLFission model with G4NeutronHPFissionData, I obtain fissions but cannot see any fission fragments. As I've read on previous threads, this model cannot produce fission fragments whereas G4ParaFissionModel does. When I use it, no fission appears.
Here is how I implement the G4NeutronHPorLFission model :
G4HadronFissionProcess* theFissionProcess = new G4HadronFissionProcess(); G4NeutronHPorLFission* theFissionModel = new G4NeutronHPorLFission(); G4NeutronHPFissionData* theHPFissionData = new G4NeutronHPFissionData();
Here is how I implement the ParaFissionModel :
G4HadronFissionProcess* theFissionProcess = new G4HadronFissionProcess();
G4ParaFissionModel* theParaFissionModel = new G4ParaFissionModel();
Uranium is built like this :
a=235.0439299*g/mole; G4Isotope* U235=new G4Isotope(name="U235", z=92., A=235, a); G4Element* elU=new G4Element(name="uranium235",symbol="U",ncomponents=1); elU->AddIsotope(U235, abundance=100.*perCent);
density = 19.1*g/cm3; G4Material* Uranium = new G4Material(name="Uranium", density, ncomponents=1); Uranium->AddElement(elU, fractionmass=1.);
I use Geant 4.9.4 p01 with Windows/Cygwin.
thanks for help
