Abstract : Tungsten/carbon(W/C) multilayers were prepared by ion beam sputtering. The properties of the multilayers were studied by low-angle x-ray diffraction, transmission electron microscopy (TEM) observation of the cross section and Auger electron spectroscopy. It was found that carbon atoms diffused into the tungsten layers and formed carbide. The measured reflectivity was in good agreement with the calculation, considering the decrease in density and the interfacial roughness. The multilayers were deposited on a concave spherical mirror and x-rays were focused by the mirror on a line-shaped image.
