Abstract

Electroformed grazing incidence mirrors were tested with x rays and were measured with an optical profiler. Their total effective areas are ≳70% of the theoretical values both for 1.5- and 6.4-keV x rays. The half-power diameters (HPDs) are ≲2 min of arc at 1.5 keV. Comparing the x-ray test result with the optical measurement, we set requirements of high-frequency roughness <14 Å and a midfrequency roughness <70 Å for a HPD < 1.5 min of arc at 7 keV. We also present a design of the mirror array telescope for high energies (MARTHE) which has a total effective area of ~1000 cm² for 7-keV x rays.
