Abstract
The experimental station for detector calibration with synchrotron radiation (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 is extracted from a bending magnet of the storage ring and monochromatized by a multilayer mirror. The first calibration procedures are to use the good calculability of the SR photon flux and the measured parameters 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 through a set of calibrated absorbing filters and at different positron energies. A description of the station, the estimations of the calibration uncertainties and preliminary results of the monochromator testing are presented.
