Wave Effect Neutron Radiographic Imaging Origins in WCNR and Prospects for Low Cost Systems

The origins of wave effect neutron test methods for advanced neutron radiography as published in World Conference on Neutron Radiography (WCNR) series has been reviewed. They include Neutron Holography demonstrated at the Dido reactor, Harwell, UK; Neutron Refraction and Small Angle Scattering demonstrated at the IR-8 reactor, Kurchatov Institute, Moscow, Russia; and Neutron Interferometry demonstrated at the ILL reactor, Grenoble, France. Each case presents encouraging evidence that the advanced techniques currently practiced at the most advanced shared-user facilities could be built upon at some lower cost, single-user facilities if the lessons of the original low cost experiments are studied.
