Abstract
The optical System composed of an X-ray silicon planar refractive lens and an X-ray planar waveguide
with air gap has been characterized with synchrotron radiation. The guiding structure consisted of two silicon plates,
clamped by permanent magnets and divided by a spacer made of thin magnetic film. The System was studied in the
energy range 8-17 keV on the Optics beamline BMOS at the ESRF (Grenoble). It was shown, that the number of
resonant modes in the beam exiting from the waveguide could be controlled by planar lens orientation, so that
minimal number of modes could be obtained. Refractive optics elements and X-ray planar waveguides are a good
combination for synchrotron sources of last génération and free electron lasers.
