| Research Abstract |
The warm-hot intergalactic medium (WHIM) is an important probe to study large scale structure of the universe fomedby the dark matter, which consists of unknown elementary particles. WHIM is also important observation target to clarify the structure and the evolution of dark baryons, which have been hardly observed so far. In this research, we developed a new type of X-ray telescope to detect weak X-rays from WHIM At first we took four reflection mirror system as abase optics and established ray tracing code for analyzing these new optical systems including extended Wolter type I optics. Using this tool, we optimized telescope parameters such as focal length, diameters and length of element mirrors and minor surface materials to maximize performances such as an effective area, a field of view, GRASP and angular resolution under the condition of assumed satellite and detector structures. Based on this study we made a quadrant model of four-reflection telescope using segmented replica foil miner made by previously used method for Suzuki. Adding to this, we developed superpolished replica mandrel and multistage full shell minor substrate to get higher performance of a replica foil minor and reduce total number of element mirrors. On the mandrel, it was achieved that figure error was has than 0.5 μm and surface microtoughness was less than 1 nm. On the monolithic mirror substrate, we tried several methods and found that a direct machining method can be used to make such substrate with figure error of 10 μm Technologies developed in this research can be utilized to make telescopes for future satellite mission such as the DIOS
