Dear FLUKA experts,
I am currently simulating a proton beam impinging on water, generating secondaries that arrive in a detector. This is essentially a two step process, in 1) generating secondaries and 2) transporting the secondaries to the detector. I simulated the production of secondaries once and would like to use it as a source.f file, in order to flexibly change detector geometry without having to resimulate the production every time.
My problem at the moment is, however, that simulating steps 1) and 2) together (end to end simulation) gives a very different result from the two separate steps (with the source.f routine) approach. Interestingly enough, if the source file consists only of photons, both methods are mostly compatible. If the source file consists also of other secondaries, they are not (simulation time far longer, generated file much larger). Am I perhaps missing something in my source.f file that takes different particles into consideration?
?I have attached my files for generating the collision tape file (to be called by the source.f routine) and end to end simulation (*_source_and_endtoend files) as well as the files to read the collision tape and simulate only the particle transport (*
