Paper Abstract

A computational model has been developed to investigate and assess possible applications for the technique of fast neutron radiography. This technique has a number of potential advantages including the ability to use a neutron source of high brightness, provided by an accelerator, and the use of the resonant structure of the total neutron cross-section to enhance the contrast. The development and implementation of the model is described and a hypothetical example is given of its application to the imaging of aluminium in alumina. In this case the model predicts that the signal-to-noise ratio could be increased by a factor of ten by decreasing the thickness of the lithium target from 150 micrometers to 50 micrometers for the reaction 7Li(p,n)7Be used, with 4.4 MeV protons, as a neutron source. The model is at present being tested experimentally.
