Monte Carlo simulation of an iron ore analyser

Abstract

The general purpose Monte Carlo code MORSE and nuclear data derived from ENDF/B-IV are used to model an iron ore analyser which detects thermal neutron capture γ rays from ⁵⁶Fe. Measurements on an actual system have been simulated. Calculated detector count rates agree, after normalisation, with measured values to within the accuracy of the calculations (∼5% at 1σ). Practical use of the model is dependent upon improving the efficiency of the calculations.
