Abstract
The idea of an X-ray waveguide has its origin in 1974 from a paper of Spiller and Segmuller1, but only then years ago2-5 it has been demonstrated that a submicrometer X-ray beam could be produced by the waveguides. From the first experiments up to now the efficiency has been improved by three orders of magnitude6, and a nanometer beam confined in two directions has been also produced7. Recently, as it will be shown in this paper, the possibility to use waveguides with laboratory sources has been also demonstrated. The unique characteristics of the beam produced by the waveguides (nanometer beam size, high degree of coherence, well defined beam profile, etc.) make it appealing for several applications in microimaging, microdiffraction, etc. In this work the principles of X-ray waveguides together with the view of the present activity and applications of this optics will be presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
