Abstract

Diffraction efficiencies of 44.8–5.4-Å x rays by a free-standing gold transmission grating of 1.0-μm period have been measured, using characteristic line radiation. Partial transparency of the grating affects the efficiency at the shorter wavelengths and causes an increase in the efficiencies for orders m ≥ 1 over the long-wavelength values. Model calculations for a trapezoidal wire cross section are in good agreement with the measured efficiencies and allow the wire cross section to be determined. Gratings of this type have a high efficiency for wavelengths as short as 5 Å and are, therefore, well suited for applications both in x-ray and extreme uv astronomy.
