Abstract

A numerical simulation was performed to check the aptitude of low-Z materials, like carbon and boron, to be used as cladding layers in planar X-ray waveguides with a beryllium core. For a particular incident beam-energy value, an optimization technique based on a genetic algorithm was used to find the waveguide layer thicknesses, which provided the highest electric field intensity resonant enhancement in the core layer. The results of C/Be/C and B/Be/B waveguide simulations for incident beam energies from 10 to 15 keV were compared with the results obtained for Mo/Be/Mo waveguides. This comparison showed that waveguides with low-Z cladding layers should provide a guided beam of high intensity.<br>
