Abstract

An imaging plate containing photostimulable phosphor material, BaFBr:Eu2+, was found to be applicable to store images for nanosecond pulses as well as quasi-continuous radiations in 4 – 35 eV photon energy range. The sensitivity, which was defined as photostimulated luminescence intensity for a given incident photon number increased with the photon energy and had a peak at 6.2 eV. The intensity of the luminescence was confirmed to increase in proportion to incident photon numbers of the radiation. The readout system was improved and then pattern images were successfully restored. The resolution of imaging plate was found to be lower than 100 μm with our system, which depends on the intensity of a He-Ne laser for restoring images.
