Re: [fluka-discuss]: Energy density distribution using USRBIN
Dear Mina,
With the cards reported, you are scoring energy deposition, not the energy of the protons.
Tough you did not specified either the beam energy nor the material, I suspect that your protons can not deposit their total energy in a single 1 mm^3 bin.
Best,
Luigi

Hello everyone,
I am struggling with understanding what I am seeing when scoring particle energy density distribution using USRBIN.
Suppose my beam particles are protons and I am looking at
1) 'BEAMPART' fluence distribution
2) 'BEAMPART' energy density distribution
3) 'PROTON' fluence distribution
4) 'PROTON' energy density distribution
For 2), I set 'Part' to 'ENERGY' in a USRBIN card and set 'Part' to 'BEAMPART' in an associated AUXSCORE card.
For 4), I set 'Part' to 'ENERGY' in a USRBIN card and set 'Part' to 'PROTON' in an associated AUXSCORE card.
My understanding is that 2) and 4) should include all protons, i.e. beam particles as wall as secondary protons. When I look at the fluence distribution, i.e. case 2), this seems to be the case. But when I look at case 4), this does not seem to be the case. I know this right away since the maximum energy is well below the beam particle energy.
Am I missing something? I have double checked my input to make sure I haven't made any stupid mistakes. Here are the USRBIN and AUXSCORE cards for case 4):
USRBIN 10. ENERGY -41. 4. 4. 15.Proton_En
USRBIN -4. -4. -6. 80. 80. 210. &
AUXSCORE USRBIN PROTON Proton_En
As laways, thanks in advance,
Mina
