A compound optical system for coherent focusing and imaging at the nanoscale is reported,
realised by high-gain fixed-curvature elliptical mirrors in combination with X-ray waveguide …

Recent studies have shown the feasibility of channeling phenomenology applications to
describe various mechanisms of interaction of charged and neutral particle beams and …

X-ray waveguides are routinely used at synchrotron light sources in imaging setups and as a
platform for experiments with quantum emitters, providing nanometer-sized confinement …

In this review work, the passage of charged and neutral beams through dielectric capillary
guides is described from a uniform point of view of beams channeling in capillaries. The …

The propagation of hard X-ray synchrotron beams in waveguides with guiding layer
diameters in the 9–35 nm thickness range has been studied. The planar waveguide …

The enhancement of x-ray-matter interaction by guiding and focusing radiation from x-ray
free electron lasers is investigated theoretically. We show that elliptical waveguides using a …

We have studied the propagation of hard x rays in a planar x-ray waveguide with a sub-20
nm guiding layer. To optimize the transmission and to minimize absorption losses, a novel …

We have studied the spatial coherence properties of a nano-focused x-ray beam by grating
(Talbot) interferometry in projection geometry. The beam is focused by a fixed curvature …

We study the propagation of hard x rays in single curved x-ray waveguide channels and
observe waveguide effects down to surprisingly small radii of curvature R≃ 10 mm and a …

We have fabricated linear tapered waveguide channels filled with air and imbedded in
silicon for the hard x-ray regime, using a processing scheme involving e-beam lithography …
