Dear Fluka experts,
I'm generating source using source.f routine which reads spectrum from file and has a SFLOOR subroutine which generates an isotropic fluence (sphere w/ r=60 cm).
How do I take into account the emission radius when I convert the USRBDX output (integrated over solid angle) to part/cm2/MeV?
I am using the following conversion when the source is just a simple beam:
[cid:5935cc82-a33f-4af7-87c8-2c34d63e2aa6]
where the third term is detector's area and the last term is the total fluence found from the integral fluence as follows:
Ftotal = F(Emax) - F(Emin)
However, this conversion doesn't work when source is a sphere.
I believe this is because the emission radius is not included since the magnitude of the scored fluence changes with emission radius.
Also, I noticed that emission sphere emits both inwards and outwards. Can I force it to emit inwards only?
I attach my source and input files.
Thank you,
Roman
