Dear fluka expert
I'm simulating 100 GeV electron beam impinging a Pb target. I'm
interested in score neutron and energy deposited in a calorimeter place
after the target. In order to have good accuracy, I have defined the
corresponding PHOTONUC card, using SDUM=ELECTNUC option. Then, as is
recommended in the fluka manual I have added a LAM-BIAS card with
SDUM=GDECAY.
The manual reads:
"10) For photons, a typical reduction factor of the hadronic inelastic
interaction length is the order of 0.01-0.05 for a shower
initiated
by 1 GeV photons or electrons, and of 0.1-0.5 for one at 10
TeV.
For electrons and positrons, a typical reduction factor is
about
5.E-4"
According to the fluka manual, I have tried different values of
parameter lambda-inelastic (WHAT(2)), starting from 5.E-4 as the manual
suggests to my case. However, it was impossible to run the code, this
takes a lot of time and then the computer becomes stuck. In this sense,
I start to increase this value, founding that for a value equal to 0.6
the code works.
So. I would like to ask if there is any problem choosing a value
different from the recommended and how this fact can affect my results?
thank you in advance.
regards,
Jilberto
