Outline of Final Research Achievements

Search and discovery of exotic particles, which is predicted but not detected yet so far are significant in particle physics and cosmology.
Main purpose of this study is research and development of key technologies to detect such particles using Michelson interferometer. In previous methods, signal of detector is generated by energy deposition by exotic particles. In this investigation, new method (by momentum deposition) is considered. The sensitivity is 10 times better than those of previous methods.
Research and development of components of detector (assembly of mirror and its suspension, cooling test, estimation of noise and so on) was almost finished. The next step is to assemble Michelson interferometer and test run for observation.
