Outline of Final Research Achievements

In order to develop novel media for wide-range neutron detection, the mixtures of photostimulable phosphors and neutron sensitive materials in which polyethylene powder was dispersed have been investigated. As a results of experimental and theoretical studies using Monte Carlo simulation and relativistic theory, it was confirmed that the wide-range neutron detection can be established without adding any polyethylene. For high-sensitive neutron detection, the mixtures of photostimulable phosphors and neutron sensitive materials was effective, while the photostimulable phosphors that has a neutron sensitive materials in its matrix was effective for high-position resolution.
