Effects of interface-engineering on the internal structure and reflective characteristics of Cr/Sc multilayer mirrors.

Record reflectivity's of R=23.8% at 3.14 nm and R=30.

Al/Zr-based multilayer mirrors with record-breaking reflectivity.

The paper reports on a new Zr/Be/Si/Al multilayer structure that provides record reflectances of up to 67% and a spectral resolution of Δλ = 0.63 nm (λ / Δλ ≈ 27) in the spectral range of 17-20 nm. It is shown that the structure has a high temporal stability of extreme ultraviolet (EUV) optical characteristics.

Stress, reflectance, and stability of Ru/Be multilayer coatings with Mo interlayers near the 11 nm wavelength.

The stress, reflectance, and temporal stability of Ru/Be multilayer mirrors, both with and without Mo interlayers, were studied. A Ru/Be MLM was found to have zero stress at a Ru layer thickness-to-period ratio of γ ∼ 0.4.

Investigation of structural and reflective characteristics of short-period Mo/BC multilayer X-ray mirrors.

The results of a study of the structural and reflective characteristics of short-period multilayer X-ray mirrors based on Mo/BC at wavelengths 1.54 Å, 9.89 Å and 17.

EUV telescope for a Cubesat nanosatellite.

This paper describes in detail a compact (2U format) telescope operating in the extreme ultraviolet range for studying the solar corona at a wavelength of 17.14 nm. The telescope objective has been built according to the Ritchey-Chrétien scheme with the following parameters: effective focal length of 381.
