Application of Nuclear Emulsion Plate on the Elementary and Nuclear Physics and Development of Multi-layered Color Emulsion Plate

Abstract

A new method to obtain three-dimensional information on nuclear ion beam tracks was developed using color multi-layered photographic materials. Commercial color films were irradiated with ion beams. The tracks were represented with a color image in which different depths were indicated by different colors, and the three-dimensional information was obtained from color changes. We also prepared a self-coating color nuclear emulsion plate which consisted of three layers including a nuclear emulsion and a color coupler. Details of this method, and advantages and limitations were discussed in comparison with a conventional method using a nuclear emulsion.
