SNAKE: A Solid Angle Calculational System.

摘要

A computer code, SNAKE (Solid Angle Calculational System For Neutron Interaction And Array K-effective Estimation),has been developed for the calculation of solid angles subtended by geometric forms composed of spherical,cylindrical,and planar surfaces,either singularly or in specified arrays,from exact analytic integral forms. This basic capability is used to provide information necessary for the solid angle method for evaluation of neutron interaction in arrays. This document outlines the methodology and use of the code.
