The project, performed by Salim Abdali, aims at studying multilayers and other X-ray optical elements with potential use in X-ray astronomy in the photon energy ranges below 0.2 keV and around the Fe K alpha line at 6.9 keV. The project is a collaboration with Finn E. Christensen of the Danish Space Research Institute. Multilayers of Co/C have been deposited on Si 111 crystals for simultaneous spectroscopy of soft and hard X-rays, utilizing diffraction in the multilayers and the substrate, respectively. In addition, LiF 220 and RAP crystals are included in the Bragg reflection panel of the Russian-Danish satellite SRG. provided with a Wolther Type I telescope. The latter has been tested at the synchrotron radiation source of the Daresbury Laboratory in England.
