| Research Abstract |
I have manufactured two multilayer mirrors. One has a pair of 40 Y２O３/Al layers and the other has a pair of 20 Mg/SiC layers. I concluded that (1) An Mg/SiC mirror has about twice higher reflectivity than that of Mo/Si, but (2) it decreases the performance under the atmosphere, (3) a Y2O3/Al multilayer mirror has higher reflectivity at 30.4nm than that of Mo/Si, furthermore (4) it can reduce the reflectivity at 58.4nm to one-fifth in comparison with Mo/Si pairs. The Y2O3/Al multilayer has enough capability to use space-borne instrument in the near-future.
