Ray-tracing program SHADOW was used to simulate X-ray propagation in capillaries with cylindrical, tapered and polynomial profiles. The results indicate efficient concentration of X-ray beams by all of these capillaries. The influences on transmission properties from geometry parameters of...

The transmission properties of X-ray in a straight capillary were studied by computer simulation with the Ray-Tracing program SHADOW. The simulation was done for 30keV photons in a SiO2 capillary with perfect smooth inner surface. The simulation indicates an effect collimation of X-rays by the...
