Dear fluka experts,
In my "usual" fluka simplified model, usbrea.inp, I am scoring the
energy in a specified region, which was hit by a proton beam. Then I am
using usbrea code to export the integrated energy deposited in this
region for different beam intensities.
The problem: I realized that, for a fixed beam energy, increasing the
number of runs, hence the number of primaries/beam intensity, does NOT
change the value of the integrated energy deposited in the target volume?!
Attached, you will find:
- usbrea_3Runs_98.bnn file: integrated binary file using flair, for 3
Runs (each of 1000 primaries, i.e. 3000 pot).
- usbrea_10Runs_98.bnn file: integrated binary file using flair, for 10
Runs (each of 1000 primaries, i.e. 10000 pot).
- Edep_3Runs.txt file: formatted file for the integrated deposited
energy in the specified region, generated by applying usbrea code on
usbrea_3Runs_98.bnn.
- Edep_10Runs.txt file: formatted file for the integrated deposited
energy in the specified region, generated by applying usbrea code on
usbrea_10Runs_98.bnn.
As you can see, whether integrate over 3 runs or 10 runs, the total
deposited energy, in the two txt file, is same in the target volume! Is
the integrated deposited energy in a volume is independent of the
intensity of the incident radiation? Or I misunderstand some physics?
Regards,
Tamer
