The MORSE Code with Combinatorial Geometry

Abstract

The combinatorial geometry allows efficient Monte Carlo radiation transport calculations of detailed three-dimensional geometries. Because regions and media are formed by combination of basic bodies such as boxes, spheres, cylinders and others, the input required of the user is both relatively simple and easily modified. The MORSE code is a multigroup neutron and gamma ray transport Monte Carlo code that may solve either neutron, gamma ray, or coupled neutron-gamma ray problems in either the forward and adjoint mode. MORSE has a wide variety of available input options, including splitting, Russian roulette, exponential transform, energy biasing, importance regions, albedo surfaces, and the scoring options available in the SAMBO analysis package. This document details the incorporation of a new version of combinatorial geometry into the MORSE code and is meant as a user's manual.
