Outline of Final Research Achievements

This research aim the directional dark matter search with super-high resolution nuclear emulsions which is solid detector with scalability.
In this term, international collaboration(LNGS, Napoli etc.) was constructed, and developed new systems for this research. By using those, directional efficiency and angular resolution was evaluated by using Ion-implant system, and original simulator was developed. These study was progress to understand the detector. In parallel, high precision analysis method using Plasmon resonance eefect was proposed and demonstrated that feasibility. In addition, intrinsic radioactivity in our device was measured quantitatively by collaboration with Gran Sasso Laboratory. These study became generic technologies for this project.
