The near-normal-incidence efficiencies of a 2400-groove/mm holographic master grating, a
replica grating, and a multilayer grating are modeled in the soft-x-ray-extreme-ultraviolet …

We characterized a laminar grating with a Mo/Si multilayer coating by using synchrotron
radiation and atomic force microscopy. The grating substrate had 2400 grooves/mm, 40-Å …

The first experimental investigation of a normal-incidence Mo–Y multilayer-coated diffraction

The design of the multilayer coatings and multilayer grating for the EIS spectrometer is
presented. The grating substrate has a rectangular laminar groove profile with 4200 …

Both classical (in-plane) and conical (off-plane) grating configurations can be used in the
spectrometer being developed for the Spectroscopy X-ray Telescope (SXT), which is …

The efficiency of a diffraction grating was measured near normal incidence in the 125–225-Å
wavelength range with synchrotron radiation. The grating pattern had 2400 grooves/mm and …

We have measured the efficiency over the range 125–225 Å of a bare ion-etched plane
laminar holographic grating made of fused silica and with 1000 grooves/mm. The measured …

Application of rigorous integral method for computing the efficiency of arbitrary profile relief
gratings used in all the optical spectral range is presented in this paper. The main progress …

MoRu–Be multilayer coatings were applied to two diffraction gratings for the purpose of
enhancing their normal-incidence efficiency in the 11.1–12.0-nm wavelength range. The …

Thin-film interference effects were observed in the normal-incidence efficiency of a 2400-
groove/mm replica grating. The efficiency was measured in the 100–350-Å wavelength …
