Description
In this work soft X-ray synchrotron radiation transmitted through microchannel plates was investigated. Primary monochromatic beam penetrates into microchannels of a hexagonally regular polycapillary structure ~ 0.4 mm thick, with channels of 10 µm hole diameter and 12 µm pitch. Fine structure of reflection and XANES spectra at the Si L-edge at the exit of SiO2 MCP has been analysed. The characterization of the X-ray fluorescence exiting by micro-channels and the transmission by hollow silicon-glass microcapillary structures is the objective of this research. The anomalous dispersion region (Si L-edge) channeling of X-rays in MCPs as well as the interaction of standing waves in a media with unoccupied electronic states has been studied.
