A neutron detector with spatial resolution of submicron using   fine-grained nuclear emulsion
  We have been developing a neutron detector with spatial resolution of submicron by loading 6Li into fine-grained nuclear emulsion. By exposure to thermal neutrons, tracks from neutron capture events were observed. From their grain density, spatial resolution was estimated. Detection efficiency was also measured by an experiment with cold neutrons.
