Abstract : A parabolic mirror system, which is capable of focussing x rays from a point source, is described. Since x rays are reflected only when the angle between the plane of the mirror and the incident ray is small, the mirror can focus only a limited portion of the total radiant x-ray flux. This grazing angle depends upon the reflector material as well as the energy of the x-ray photon. The intensity of reflection for a few suitable materials is also presented. If the source is not a perfect point source, the x-ray beam is divergent. The relation between source size and beam divergence angle is also discussed. (Author)
