Re: scoring of neutron

Dear Mojdeh,

The input file is missing PHOTONUC card.
The region named "ioncham" (not "ionchamb") is not assigned any
material, which makes it a black hole by default.
Also, are you sure you want your beam divergence to be isotropic?
Please, double check your BEAM and BEAMPOS cards.

Cheers
