Abstract :
An optical stimulated luminescent (OSL) material α-Al2O3:C is sensitized for neutrons. Basic performances of neutron sensitivity, linearity, and fading characteristics are studied for three types of neutron sensitive OSL sheets using a prompt OSL reader. Neutron imaging is also studied using an imaging OSL reader. Preliminary results of neutron image will be shown in this paper.
