Popis: Recent advances in grazing incidence X-ray optics using synchrotron radiation sources have stimulated the need for basic research in high quality mirror materials for novel applications. In this paper we communicate the results of the first measurements of glazing angle X-ray reflectivity (XRR) of speculum metal mirrors using synchrotron radiation sources. Our results agree with similar measurements made in polished speculum gratings by Arthur Compton and his collaborators during 1923 using ordinary X-ray tubes. Our experimental investigations are based on synchrotron radiation research facilities (Indus 2) maintained by Govt of India in Indore . Variations in the XRR with grazing angles of incidence and X-ray energy for cast, thin film and electron irradiated samples of speculum metal will be discussed in this paper.
