Abstract

X-ray micro-calorimeters such as the Soft X-ray Spectrometer on board ASTRO-H will enable precise spectroscopy of iron K lines. To exploit the full power of the high-energy resolution, X-ray telescopes with a large effective area around 6 keV are essentially important. We designed a Wolter-I X-ray telescope with Ir/C multi- layer mirrors to enhance the effective area at around 6 keV by the principle of Bragg reflection. We assumed a diameter of 110 cm and a focal length of 110 cm for our telescope. Our simulation suggests that the effective area averaged in the 5.7{7.7 keV band could be 2000 cm².
