| Outline of Final Research Achievements |
We aimed to develop the detection system of fine radiation-tracks due to the dark matter recorded on nuclear plates with ultra-fine-grain emulsions as a part of international project for the dark matter search NEWS(Nuclear Emulsion for WIMPs Search). We studied the methods of fluorescence labeling and surface-localized-plasmon-resonance emission for the super-high-resolution microscopy in order to detect fine tracks smaller than the resolution of optical microscope, and observed fine images not-resolving on the microscope. Technologies for nuclear plates such as sensitization method for ultra-fine grain emulsions and noise removal were developed.
