“…X-ray multilayer mirrors (MLMs) are used in various fields of science and technology, such as solar astronomy, X-ray lithography, X-ray microscopy and spectroscopy (Martı ´nez- Galarce et al, 2013;Chkhalo & Salashchenko, 2013;Akhsakhalyan et al, 2017;Fogelqvist et al, 2017). One of the important practical applications of X-ray multilayer mirrors is monochromatization and nanofocusing systems at synchrotron radiation stations (Rashchenko et al, 2020;Morawe, 2019;Morawe et al, 2017;Sawhney et al, 2011;Chkhalo, Garakhin, Malyshev et al, 2022;Mimura et al, 2010;Yumoto et al, 2022;Koyama et al, 2022). The possibility of enabling the mirror to intercept as much of the synchrotron radiation beam as possible is one of the aspects that must be taken into account when developing reflective elements for such applications.…”

The results of a study of the structural and reflective characteristics of short-period multilayer X-ray mirrors based on Mo/B4C at wavelengths 1.54 Å, 9.89 Å and 17.59 Å are presented. The period of the samples varied in the range 8–35 Å. The average widths of the interfaces were ∼3.5 and 2.2 Å at one and the other boundaries, with a tendency for weak growth with any decrease in the period. The interlayer roughness was ∼1 Å. The research results indicate promising prospects for the use of multilayer Mo/B4C mirrors for synchrotron applications.

We address the problem of eliminating measurement errors by filtering in such a way as to minimize the smoothing of real data while attempting to remove effects introduced by hardware functions. A critical analysis was performed of a range of existing filters for X-ray mirrors with subnanometer precision, including not only classical smoothing filters but also specialized filters designed for filtering X-ray mirror problems. Because the standard filters under consideration did not allow us to remove diffraction rings and peaks for our X-ray mirrors, we developed a novel technique for such image filtering. The proposed Fourier filtering of the interferometer data allows us to eliminate some of the measurement errors, thereby increasing the accuracy of the measured X-ray mirrors in the subnanometer range.
