Thank you for the comment. I have add the material for Deuterium Gas as follows:
// Deuterium Gas ( with pressure 7.0 atm and room temp 293.15K)
G4Isotope* iso_H2= new G4Isotope(name="D",iz=1,n=1,a=2.014*g/mole); G4Element* ele_H2= new G4Element(name="Deuterium Gas",symbol="D", ncomponents=1); ele_H2 -> AddIsotope(iso_H2, abundance =100.*perCent); DeuteriumGas = new G4Material("Deuterium Gas",density= 0.00124*g/cm3, ncomponents=1,kStateGas, 293.15*kelvin, 7.0*atmosphere); DeuteriumGas->AddElement(ele_H2,fractionmass =1);
Definition of Gas looks OK to me according the tutorial. But Still I can not see neutron. My output for 20 MeV deuteron on D, still looks like follows.
### Run 1 start /vis/scene/notifyHandlers Start Run processing. Track #2 of He3[11316.3] E(MeV)= 13.33901 ID= 1 Track #2 of He3[11316.3] E(MeV)= 13.33901 ID= 1 Track #2 of He3[11316.3] E(MeV)= 13.33901 ID= 1 Track #2 of He3[11316.3] E(MeV)= 13.33901 ID= 1 Track #2 of He3[11316.3] E(MeV)= 13.33901 ID= 1 Run terminated. Run Summary Number of events processed : 20000
If I change material name (i.e. to air ), I can see neutron.
Do I miss something in my material definition? or what is wrong?
