Dear Fluka Experts,
I want to simulate a neutron source with following definition of its energy spectrum.
For energies 0 eV - 0.625 eV (Maxwell distribution)
for energies (0.625 eV- 122 keV) (as function of 1/E)
for energies (122keV - 10 Mev) - (as per crannberg watt function for fast neutrons)
How do i carry this out in the source.f? Any beginner inputs would be very welcome. I am attempting a activation calculation of SS in reactor environment.
Could anyone guide to a document on source.f that explain all the variables and its importance. An example source.f file where particles energy has been sampled from a given probability distribution function will be very much helpful and much appreciated.
