Outline of Final Research Achievements

In this research, we increased the nuclear emulsion gel production capability up to 700kg/year and the emulsion film production capability up to 300m2/year. Using this capability, we supplied nuclear emulsion films to the following projects and accelerated each projects and fields, 1) NINJA experiment at JPARC for the study of low energy neutrino interactions, 2) GRAINE project for the balloon borne large aperture and high precision gamma-ray telescope, 3) Cosmic-ray muon radiography to investigate the inner structure of large scale subjects like Pyramids. In parallel, we realized the extension of the crystal size selection from 20nm to 1.2 microns. By this extension, we can select the crystal size suited to the purpose. Using super fine crystal gel of 10 nano-meter size, we developed the experiment for dark matter directional detection, heavy ion experiments and high precision neutron detection.
