Application of imaging plate neutron detector to neutron radiography

As an imaging plate neutron detector (IP-ND) has been available for thermal neutron radiography (TNR) which has high resolution, high sensitivity and wide range, some basic characteristics of the IP-ND system were measured at the E-2 facility of the KUR. After basic performances of the IP were studi ed, images with high quality were obtained at a neutron fluence of 2 to 7 x 10(8) n cm(-2). It was found that the IP-ND system with Gd2O3 as a neutron converter material has a higher sensitivity to gamma-ray than that of a co nventional film method. As a successful example, clear radiographs of the B at view for the fuel side plates with boron burnable poison were obtained. An application of the IP-ND system to neutron radiography (NR) is presented in this paper. (C) 1999 Elsevier Science B.V. All rights reserved.
