Description
Summary:We have built a prototype of thin-foil substrates for the future mission with a large X-ray telescope. In future X-ray missions, the understanding of the early universe to reveal the evolution of the universe will become an important issue. For this purpose, large telescopes with high-spatial resolution up to 10 ′′ are required. Using a stamping die with high accuracy, we have successfully press-formed thin-foil substrates into an almost accurate form of the Wolter type-I optics, which reflect X-rays twice with their confocal paraboloidal and hyperboloidal reflectors. The accuracy of the shape has reached to
