Polycapillary Optics Beam Divergence

摘要

This paper is about the beam divergences of polycapillary optics. The definitions and measurement methods of polycapillary optics beam local divergence and global divergence are given. Factors like source spot size, optic input focal distance etc. for determining the beam local divergences are analyzed. Some simulation and experimental results for the polycapillary optics, which are used for X-ray diffraction and X-ray lithography, will also be presented.
