Abstract

Different radial capillary layers give different contributions in x-ray radiation field at Kumakhov lens of halflens exit. In case of halflenses transforming divergent beams into quasiparallel ones it can essentially influence an exit quasiparallel beam uniformity; in case of lenses and halflenses transforming quasiparallel beams into covergent ones focus position and focal spot uniformity depend on radial layers of capillary structure. This question is essential both for studying and using Kumakhov capillary optics. Different radial layers of Kumakhov lens are experimentally studied in this work from the standpoint of their influence on a focal spot forming.
