3. NATURE OF PHYSICAL PROBLEM SOLVED
The SAM-CE system comprises two Monte Carlo codes, SAM-F and SAM-A. SAM-F supercedes the forward Monte Carlo code, SAM-C.
SAM-A is an adjoint Monte Carlo code designed to calculate the response due to fields of primary and secondary gamma radiation.
The SAM-CE system is a FORTRAN Monte Carlo computer code designed to solve the time-dependent neutron and gamma-ray transport equations in complex three-dimensional geometries.
SAM-CE is applicable for forward neutron calculations and for forward as well as adjoint primary gamma-ray calculations. In addition, SAM-CE is applicable for the gamma-ray stage of the coupled neutron-secondary gamma ray problem, which may be solved in either the forward or the adjoint mode.
Time-dependent fluxes, and flux functionals such as dose, heating, count rates, etc., are calculated as functions of energy, time and position. Multiple scoring regions are permitted and these may be either finite volume regions or point detectors or both. Other scores of interest, e.g., collision and absorption densities, etc., are also made.
