Terahertz radiation is considered as a promising tool for a number of applications. One possible way to emit THz waves is to pass short electron bunch through a waveguide structure loaded with dielectric*. In our previous papers, we have analyzed this problem in both approximate** and rigorous*** formulation. However, we have encountered certain difficulties with calculations. In the present report, we are starting to develop another rigorous approach based on mode-matching technique and modified residue-calculus technique. We consider the radiation from the open-ended dielectrically loaded cylindrical waveguide placed inside regular cylindrical waveguide with larger radius. We present structure of reflected and transmitted modes and typical radiation patterns from the open end of larger radius waveguide.

The next generation light sources such as diffraction-limited storage rings and high repetition rate free electron lasers (FELs) will generate x-ray beams with significantly increased peak and average brilliance. These future facilities will require x-ray optical components capable of handling large instantaneous and average power densities while tailoring the properties of the x-ray beams for a variety of scientific experiments. In this paper we report on research and development of a single crystal diamond compound refractive lens. Diamond is the best material for high heat load applications. Moreover single crystal lens preserves coherence of the x-ray beam because scattering from grain boundaries, voids and impurities, typical for current beryllium lenses is minimized. A set of two-dimensional single crystal diamond lenses had been fabricated by fs-laser cutting and tested at Advanced Photon Source (Argonne).
