NeXT Hard X-ray Telescope

摘要

NeXT is Japan's 6th X-ray astronomical observatory following to ASTRO-E2. The launch is currently scheduled in 2010. One of the main goal of NeXT is to explore the hard X-ray Universe with newly developed hard X-ray telescope. The hard X-ray telescope utilizes multilayer-supermirror and high-throughput thin-foil optics technology. Performance of the hard X-ray telescope has been demonstrated through InFOCμS balloon experiment. This paper describes principle, design, and technology background of the Hard X-ray Telescope on board NeXT.
