Abstract:
The possibility of focusing (concentration) of long-wavelength X-rays by thick spherically bent and planar microchannel plates has been studied experimentally and theoretically. The electrodynamic simulation of emission from a finite antenna array consisting of noninteracting emitters, which are hollow microchannels, has been performed. It has been shown theoretically that the parallel beam of synchrotron radiation can be efficiently focused not only by a spherical microchannel plate but also by a pair of plane-parallel plates.
The experimental data used in this work were obtained within project nos. 18106366-ST and 191-07912-ST supported by Helmholtz-Zentrum Berlin BESSY II (Berlin). This work was supported by the Southern Federal University.
