Paper Abstract

Bragg diffraction with mosaic crystals is one of the techniques proposed to realize focusing telescopes for hard x- ray (greater than 10 keV) photons. The best candidate material for this application is pyrolytic graphite. Indeed, this crystal is characterized by a very high reflection efficiency, even if it is produced on a very limited scale. In this paper we investigate the possible use of other materials, with a larger commercial availability. In particular we propose the use of polymeric crystalline films. These materials are extremely attractive not only for their lower costs than pyrolytic graphite, but also because they are well suited for good mechanical processing. Here we discuss perspectives and problems related to the construction of Bragg telescopes based on polymeric fibers.
