Dear FLUKA experts,
Instead of a monochromatic beam, I want to introduce isotropic radiation beams that are placed in the void and are randomly sampled around a given radial range (from 0 to pi in my case, see red half-circle in the figure), or if a radial range cannot be given, around the whole void (so from 0 to 2pi).
Can this be done in FLUKA?
So for example, if I run 100,000 neutron particles, these are randomly distributed over the circle length from 0 to pi. In this case, should also a centre be defined toward which the particles are directed to?
In other words, this is much alike a GCR event. The reason why I am not using FLUKA’s GCR card (and the other necessary ones) is because I am using data from an external source for this and my case is on the Martian surface.
I looked at the documentation, in particular SPECSOUR and BEAMSPOT from the FLUKA Advanced source definitions lecture, but I am not sure if I’m going in the right direction with this for my case.
Many thanks in advance.
With kind regards,
