Dear Ghazaleh,

As I understand it FLUKA does not track to eV but the limit is around 1keV. The typical limit in Geant4 is 100 eV but you need to be
very careful of what cross section data is being used in these limits. The eV tracking and DNA damage work done in Geant4 is in the
Geant4-DNA package which has been specifically written to do this. I recall that currently this works for water only.

You should be able to set the energy of the proton beam to 10 keV in the normal way:

  BEAM -1.E-5 0.0 0.0
     1.0PROTON

I can simulate energies of 1keV and 10keV without a problem myself.

I hope this is some help.

Seb

Dear FLUKA users and Expers
Hello


I'm trying to simulate DNA damage due to proton by FLUKA.
When the beam energy is in the Range of MeV, FLUKA produce output. For tracking DNA damage it needs to follow beam particle energy
to KeV and eV too. As I know Geant4 can track energy to eV range. Can FLUKA track beam energy to eV? If yes how?

And I want to define a beam of proton with 10KeV Energy but I don't know how define this energy in my Input file.


I put PRECISIon in SDUM of Default card and beam card is:


BEAM -1.E-6 0.0 0.0
     1.0PROTON

but it's not work.

In advance, thank you for your help.
