Dear Fluka Experts,
I am running a fluka simulation that requires sampling my source from a histogram distribution. The source_newgen.f file says I do not need to normalize the bin value dN/dE but I have two problems.
- Uising the AmBe ISO spectrum: page 14 and 17
This spectrum is reported as the Source strength Bi[s^-1] normalized such that sum(Bi) = 1s^-2. To get the dN/dE from here, I proceeded by dividing the Bi by the bin width Delta_E but the results obtained from Fluka don’t make any sense. Is this right? IF not, then what is the correct approach?
- Another Spectrum.
In this second specrtum, it is reported the spectral strength Phi(E).Ec against Ec and shown in the file. To proceed, I juts let Phi(E) = dN/dE = (Phi(E)*Ec)/Ec, then I computed the bin width using the formula reported. Is this the correct approach?
- I also computed the normalized dN/dE as well as the CDF from both spetra but these three approaches all produce three different simulation resluts from FLUKA.
kindly let me know and I will be grateful. Also find attahced the useful files
