Title: Transport calculation of scattering line spread function for neutron radiography

Abstract

Neutron radiography is a valuable nondestructive testing tool to image objects invisible to X rays. While the absorption and scattering of neutrons through the object materials provide the image of the object under study, neutrons scattered off the beam direction contribute toward image degradations. To account for the scattering effect, the authors obtain the line spread function (LSF) K{sub {ell}} by solving the two-dimensional neutron transport equation for a line source through a successive collision approach. The analytic results for K{sub {ell}} are compared with experimental data obtained through a knife-edge experiment at the Ford Nuclear Reactor (FNR) and with Monte Carlo calculations.
