| Outline of Final Research Achievements |
In this study, a new ultra-precision machining method of metal mirror substrate for neutron reflection has been proposed. The neutron reflection has designed to ellipsoidal shape. It is necessary to secure a high surface roughness (less than Ra0.3nm) and higher form accuracy. In this research, the process of ultra-precision diamond turning and super smooth polishing process had been developed. In the polishing, using a rotation & revolution type polishing method (RRP), a good surface roughness of mirror substrate for neutron reflection can be created.
