Modeling the Transmission of Curved Neutron Guides with Non-Perfect Reflectivity

Published

Author(s)

David F. Mildner

Abstract

Analytic expressions for the transmission of a curved neutron guide including reflection losses are contrasted. The expressions are derived by considering the distribution of the number of reflections as a function of grazing angle at the outer surface. The results are compared with simulation results and with those from approximate analytic expressions using the mean number of reflections. We find the empirical model that best fits the simulations.
