Microscopic cross section generation

Post by francois.vh » Tue Feb 04, 2014 1:41 pm

Is it possible to add some microscopic cross sections to the broad group cross sections generated per universe? In particular, in order to deplete with our core simulator, we require: (LaTeX markup)

\int dr\int dE N_i(r) \sigma_i^t(r,E) \theta(r,E) / ( N_i * \int dr \int dE \theta(r,E) )

where :
N_i(r) is the number density distribution of isotope i in the volume
N_i = 1/V \int dr N_i(r) is the average number density of isotope i in the volume
\sigma_i^t(r,E) is the microscopic cross section of isotope i for reaction t
\theta(r,E) is the flux

It would nice if one could specify the universe, with an additional list of isotopes within that universe for which microscopic cross sections should be generated. For certain reactions, I can probably use a detector response function, but I also need microscopic differential cross sections. I've noticed that some microscopic reactions are already printed in the output file, so I'm not sure if this functionality already exist, or is planned.

Sound's like a good idea. I'll add this in my TODO-list.
