The development of the light-weight silicon carbide mirrors for the ASTRO-F missionis described in this paper. These mirrors are made of a sandwich-type SiC material, consisting oflight porous core and dense CVD (chemical vapor deposition) coat of SiC. The primary mirror hasa diameter of 710 mm and weighs only 11 kg. Combined with the secondary mirror of the sametype, they form Ritchey-Chretien type telescope (F/6), which is cooled down to 5.8 K. Fabricationof the small-scale test SiC mirror has been successful which shows very little deformation of thefigure at liquid-helium temperatures. Another type of the SiC coated mirror has been tested whichhas the same size as flight model, but of which core is made of graphite. At present, polishing ofthe flight-model primary mirror is going on. Construction of the flight model telescope system willbe finished in 2001. |
