Abstract:The aim of this article is to describe a mathematical model and an associated numerical method for the basic problem of evaluating the void fraction of a slab material from the responses of a typical sourcedetector system for backscattered neutrons. The mathematical model and void fraction evaluation method reported herein: i) enable us to treat explicitly and exactly a mixed neutron beam, i.e. a neutron beam consisting of a monodirectional component with normal incidence upon the slab material and a component… Show more
