Wave propagation of induced soft X-ray radiation (VUV) though μ-capillary holes of ordered structures of glass micro-channel plate: Comparison among theoretical and experimental data

Soft x-ray reflection and transmission spectra of radiation propagating inside micro-channel plates have been analyzed in the framework of the wave approximation. We researched experimental spectra collected at the exit of micro-capillaries under total X-ray reflection condition and supported them with theoretical calculations. X-ray and fluorescence yield due to the grazing incidence reflection phenomenon have been investigated with respect to the geometry of channel walls. The features of soft X-ray fluorescence spectra of radiation propagating inside micro-channel plates have been studied in the framework of wave approximation. It was shown that the wave penetrating through cladding material substantially modifies the wave field near the waveguide surface. Diffraction phenomena at the exit of a hollow X-ray waveguide (with real and imaginary parts of permittivity) were investigated using the model of Fraunhofer diffraction of waves at far zone.
