| Outline of Final Research Achievements |
In order to realize a neuron microscope, we are developing Wolter type I supermirror as a magnetic imaging device that is a rotationally symmetric mirror consisting of an elliptical mirror followed by a hyperbolic mirror. In this study, NiC/Ti supermirror device is fabricated by demolding of the multilayer deposited on the surface of the high-precision mandrel. Figure error of the mandrel is corrected by numerically controlled plasma chemical vaporization machining (NC-PCVM) which can correct the figure error deterministically without forming subsurface damage.NC-PCVM had been used to correct the flatness and/or thickness distribution of the plane substrate with nanometer order accuracy. We achieved submicrometer order figure accuracy (230 nm) by applying NC-PCVM figure correction with compensation of surface temperature change caused by plasma irradiation. We found the parameters of the coating, electroforming and demolding processes on the self stand supermirror.
