Fast neutron radiography(FNR) is an attractive non-destructive inspection technique in terms of the excellent penetration characteristics of fast neutrons in matter.FNR can be the only approach for non-destructive inspection of industrial products which are too thick or too dense for thermal neutron radiography.The imaging plate detector

a two dimensional detector for ionizing radiations

can be over 100 times more sensitive than conventional radiography films.At Institute of Nuclear Physics and Chemistry

China Academy of Engineering Physics

an FNR system based on D-T accelerator neutron source has been established

with a spatial resolution of 1 mm.In this paper

we report its detector structure and the laboratorial test results.
