The project of end-station for high-resolution soft X-ray emission spectroscopy on VEPP-4M storage ring
Modern X-ray emission spectroscopy (XES) is a powerful and effective method for studying the elemental composition, electronic and atomic structure of various substances and materials. The XES data allows comparing features of the electronic and atomic structure of the studied substances with their physicochemical properties to predict on this basis properties of new substances and materials. Despite the highly informative XES method, in our country specialized end-stations for studying electron and spatial structure with soft X-ray emission spectra using synchrotron source is lacking. In this connection, the Nikolaev Institute of Inorganic Chemistry of SB RAS and the Budker Institute of Nuclear Physics of SB RAS are working to create a high-resolution X-ray emission spectroscopy end-station for the study of the elemental composition and electronic structure of light-element compounds in "Siberian Synchrotron and Terahertz Radiation Center (SSTRC)" based on VEPP-4M. As expected, the station will use the "Cosmos" beamline based on the VEPP-4M storage of Budker Institute of Nuclear Physics of SB RAS and the ultra-soft X-ray spectrometer "Stearat", developed at the Institute of Inorganic Chemistry of SB RAS. The report presents the main parameters of the planned station and the current status of the work on its creation.
The reported study was funded by RFBR according to the research project № 18-03-01061 A. The work relating to the development of the station is carried out using the infrastructure of the Shared-Use Center "Siberian Synchrotron and Terahertz Radiation Center (SSTRC)" based on VEPP-4M of BINP SB RAS.
