22 jan 09 Interaction e- et gamma de 100 MeV sur Tungsten

J’ai cherché désespérément  ces informations pour cross checker ma simulation Geant4:
Nombre particules secondaires créées et leur pertes d’énergie dans la cible.
Taille de la cible de Tungsten(G4_W densité 19.3 g/cm3) 3.5mm (*20cm*20cm)
Uniquement les processus EM pris en compte pas de flag hadronique i.e pas de création de neutrons 

 

1) Run  10000 gamma de 100 MeV

Gamma
Mean Number per Event : 3.127400 
Mean Kinetic Energy : 22.142556 MeV +- 37.196105 MeV 
Energy deposited in the target per incident particles  0.133872 MeV 

Electrons
Mean Number per Event : 0.406800 
Mean Kinetic Energy : 30.026098 MeV +- 24.451613 MeV 
Energy deposited in the target per incident particles  3.404414 MeV 

Positron
Mean Number per Event : 0.366600 
Mean Kinetic Energy : 33.335758 MeV +- 23.974807 MeV 
Energy deposited in the target per incident particles  2.190985 MeV 

Soit 5.73 MeV déposée dans la cible de tungstène par gamma incident

2) Run  10000 e- de 100 MeV

Gamma
Mean Number per Event : 6.670000
Mean Kinetic Energy : 7.301013 MeV +- 13.162204 MeV
Energy deposited in the target per incident particles 0.345439 MeV

Electrons
Mean Number per Event : 1.068500
Mean Kinetic Energy : 31.868788 MeV +- 24.521092 MeV
Mean Polarization :0.000000 +- 0.000000
Energy deposited in the target per incident particles 12.372011 MeV

Positron
Mean Number per Event : 0.183000
Mean Kinetic Energy : 14.930346 MeV +- 13.545201 MeV
Energy deposited in the target per incident particles 1.234059 MeV

Soit 14 MeV déposée dans la cible de tungstène par e- incident
