Focusing of long-wavelength X-rays by means of spherical and planar microchannel plates

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.
