Optimization of a neutron image plate detector with low gamma-sensitivity
Recent experimental studies on new materials (storage phosphors and neutron converter) to be used in a low gamma-sensitive neutron image plate detector have been performed at the Research Center Julich and Darmstadt University of Technology.

Recent experimental studies on new materials (storage phosphors and neutron converter) to be used in a low gamma-sensitive neutron image plate detector have been performed at the Research Center Julich and Darmstadt University of Technology. It was shown that a mixture LiF + KCl: Eu2+ (or KBr:Eu2+) features a higher neutron/gamma signal ratio compared to BaFBr:Eu2+ mixed with Gd as in commercially available neutron image plates. However, the smaller neutron capture cross-section of Li-6 in comparison with Gd requires the use of significantly thicker recording layers. This article presents the results of numerical estimations for the performance of such a detector. The use of image plates with a thick recording layer and a regular cell structure allowing for the increase in spatial resolution (pixelated image plate) is discussed. (C) 2004 Elsevier B.V.
