✦ Synopsis

Glass-ceramic thermal neutron imaging plates (NIPs) recently reported have been further developed for use in neutron radiography. The plate consists of nanocrystallites of the storage phosphor BaCl 2 :Eu 2+ embedded within a neutron-sensitive lithium borate glass-matrix. A new generation of samples, enriched with both 10 B and 6 Li with thicknesses in the range 280-500 mm have been studied. Neutron images were read out using a Fuji BAS2500 imaging plate scanner and the quality of the images obtained was comparable to those recorded on a commercial NIP. Details of the response to neutronirradiation as well as the obtained spatial resolution of the images are presented. The neutron absorption and radiation hardness of the materials studied is also measured.
