Metrological synchrotron radiation station “Cosmos” is functioning in the Siberian Centre of Synchrotron Radiation. The purpose of the station is the development and implementation of metrology methods in the soft X-ray (80 – 5000 eV) and vacuum ultraviolet (4 – 100 eV) ranges. In order to provide such a wide spectral range the station has two monochromators, which use multilayer mirrors, diffraction gratings and Si (111) crystals. Also at the station is carry out works on the measurement of the spectral transmission of soft X-ray filters, the definition of the spectral characteristics of the TER mirrors, multilayer mirrors and crystals at the mentioned spectral range. The report presents the main parameters of the station, a description of its layout, of its monochromatic system and its reference detectors. The specification of basic metrological procedures used at the station for calibration of the various detectors is presented too.
