Abstract
We investigate the spectral characteristics of new focusing multilayer structures used as dispersive elements in a high-transmission X-ray spectrometer with cylindrical geometry (Hamos scheme): W/B4C structures in a wavelength range of λ = 8.0−9.5 Å and Cr/Sc structures in a range of λ = 30−40 Å (the range is not accessible for natural crystals). The results of demonstration experiments on laser-produced plasma spectra recording are considered. It is shown that the luminosity of a Hamos spectrometer with multilayer dispersive elements is an order of magnitude higher than the luminosity of grazing-incidence grating spectrographs with a comparable spectral resolution.
