Publication date: 2016 Source:Physics Procedia, Volume 84 Author(s): Evgeniy Korotaev, Mikhail Syrokvashin, Anastasia Fedorenko, Anton Nikolenko, Mikhail Mashkovtsev, Pavel Zavertkin, Denis Ivlyushkin, Mikhail Mashkovtsev, Pavel Zavertkin, Denis Ivlyushkin The experimental equipment of the metrology station “Cosmos” was adjusted for obtaining soft X-ray emission (XES) and absorption (XANES) spectra of reference samples. In the present work were used two different optical schemes: flat (Bragg-scheme) and cylindrically bent crystals (Johann scheme). Experimental XES and XANES spectra were compared with the spectra obtained on a laboratory X-ray spectrometer and the results of the quantum-chemical calculations.
