Paper Abstract

In order to decrease focal spot size and to preserve at the same time radiation capture angles polycapilaary lenses are made asymmetrical-inlet capillary diameters are much greater than outlet ones. Usually x-ray radiation propagation through polycapilaary lenses is considered by means of x-rays propagation simulation using Monte-Carlo method. In this work statistical approach is used allowing to analyze in details the process of photons escape from total external reflection regime. Formerly statistical approach was applied to analyze surface roughness influence on x-ray propagation through straight capillaries having constant cross-section diameters. In this work this approach is generalized on bent capillaries with changing cross-section.
