Abstract
The experimental station for detector calibration with synchrotron rad iation (SR) in the photon energy range of 0.1-1 keV has been designed and constructed at the storage ring VEPP-2M. SR from a positron beam i s extracted from a bending magnet of the storage ring and monochromati zed by a multilayer mirror. The first calibration procedures are to us e the good calculability of the SR photon flux and the measured parame ters of the multilayer monochromator when the calibration is performed in a monochromatic beam, or the reconstruction of a detector spectral sensitivity from detector signals measured in ''white'' SR beam throu gh a set of calibrated absorbing filters and at different positron ene rgies. A description of the station, the estimations of the calibratio n uncertainties and preliminary results of the monochromator testing a re presented.
