Dear all,
I ma Marine, "a newer”
I am starting to use FLUKA and to learn it I am doing simple examples.
For example I am comparing FLUKA results for proton Bragg peak in water at
different energies with the data of NIST (PSTAR). I have good agreement for
proton energies until to 300 Mev (see attached file example 200 Mev) and
within this range I see clearly the Bragg peak. For energies above this
value the energy deposition change and the Bragg peace start to disappears.
For example for 2 GeV protons energy (see attached graph) the graph seems
more similar to electron deposition.
Is there any physics in the code that i am not accounting for ?
In addition I would like to ask how I can select the particle energy in
which I am interested.
To let you know now i am using the USRBIN card but I cannot find the way to
discriminate the particle energy.
I have similar problems also with electrons but let go step by step.
regards
Marine
