Dear FLUKA- Users,
Object of my Simulation is a Container for radioactive waste (=boron water);
Co-60 volume beam. I want to score the fluence (caused by primaries) outside the
container. For scoring I created a sphere of air und used USRTRACK to score the
fluence inside this sphere.
I want to apply Importance Biasing on my Simulation. I want good statistics only
in the direction of the detector, so I cut a part of the wall in several layers
(each has the thickness of one half-value-layer). With each layer I doubled the
Importance to compensate the attenuation.
I run the simulation with 5*200000 Primarys. The USRBIN-plot seems strange to
me. Am I right in the assumption, that despite the too small number of
primaries, the USRBIN-plot should show a much larger fluence in the direction of
my interest.
My suspicion is that my BIASING-Cards are ignored by FLUKA?!
Please can somebody explain the problem and optimally correct my inpit-file (see
the attachment).
Best regards,
Alexander
