Короткопериодные Многослойные Зеркала Для Высокоразрешающего Монохроматора Многослойное Зеркало/Кристалл

Abstract

The paper presents the results of studies of W/B4C multilayer structures with small periods for their use as the first mirror in a two-mirror soft X-ray monochromator at the KOSMOS station of the VEPP-4M synchrotron. It is shown that even if the periods of the mirror and the RbAP crystal coincide, when operating in a wide wavelength range, the Bragg angle must be adjusted due to the stronger refraction in the W/B4C multilayer mirror.
