[fluka-discuss]: Sampling from fluence using Source routine

Dear friends,

I would like to sample from fluence by sampling the energy uniformly and adjusting the weight accordingly.
I have a few questions please:


1. Must a weight be an integer? Can the fluence spectra (photons per MeV per incident electron in my case) be multiplied for biasing?

2. Would it effect the usage of secondary particles biasing with the bias card?

3. In the Source.f subroutine the particle weight is dealt with at those lines:
           * Wt is the weight of the particle
             WTFLK (NPFLKA) = ONEONE
             WEIPRI = WEIPRI + WTFLK (NPFLKA)


Can the location of these lines in the subroutine be modified?
Can one please give an example of a correct way to modify the weight.


Thanks in advance,

Sion Koren, PhD, DABR
