Abstract
An imaging plate (IP) was excessively irradiated by 250 MeV proton beam up to 4.3 x 10(13) protons/cm(2) in order to examine the resultant radiation d amage. As a function of proton fluence, variations in photo-stimulated lumi nescence (PSL) signals were evaluated by comparing with the region without previous extensive proton irradiation on the same IF. Notable deterioration of PSL signal was found for the fluence more than 5 x 10(12) protons/cm(2) . Furthermore, partial recovery of the deterioration was evidently observed , which was promoted by keeping the IP at 50-70 degrees C. (C) 2000 Elsevie r Science B.V. All rights reserved.
