An Approximation to Time-Dependent Neutral Particle Transport in a Slab.

Abstract

An approximation to neutral particle transport in energy, space, and time through a thick slab shield is developed. A space independent multigroup rate equation, modified to allow particle leakage from a system of finite size, is solved to provide an expression for the total particle population as a function of time. Spacial dependence is determined exactly for unscattered particles and assumed for scattered particles. This provides a time, space, and energy dependent source of secondary radiation which is transported to a detector by point kernel integration. This approximation is demonstrated by comparison to experimental data. (Author)
