Paper Abstract

A series of prototype blazed reflection gratings, designed for incorporation in a satellite-borne, high efficiency, moderate resolution, astronomical x-ray spectrometer, have been tested for x-ray reflectivity in the relevant spectral orders. Both mechanically-ruled and ion-etched holographic master and replica grat-ings produced by various manufacturers, have been measured at 8.34 A, 13.34 A, and 44.7 A. We find near theoretical performance from a particular ion-etched sample and from one of the mechanically ruled samples. The other mechanically ruled samples exhibit lower efficiency, which can in part be ascribed to imperfections in the groove profile. A comparision between scalar diffraction theory and the rigorous electromagnetic calculations of grating efficiency for these samples is also presented.
