“…Angular intensity distributions obtained when the incidence angle is θ = 5° and the energy of the quanta of excitation radiation is E = 120 eV: (1) is the experimental distribution, (2) is the theoretical distribution of excitation radiation at the MCP output, and (3) is the theoretical distribution of reflected radiation emerged from the microchannels. 6 8 10 4 Angle φ, deg The discrepancy between the intensities of peaks conforming to positive and negative angles (Fig. 6) can be explained by the fact that, in the detector's rotation plane (Fig.…”

Experimental and theoretical studies of the angular X-ray-intensity distribution are performed at the output of microchannel plates under the condition that monochromatic radiation is incident on the microcapillary walls at grazing angles. The primary-radiation angles and energies at which a synchrotronradiation beam excites fluorescent X-rays propagating through polycapillary structures are determined. In the case of X-rays passing through microcapillaries, the fine structure of their spectra is investigated at energies corresponding to the anomalous dispersion region of the SiL 2, 3 and OK absorption edges. Theoretical calculations are carried out using a model involving a transition layer on the microchannel surface.

“…As compared to parallel-plate waveguides [6], the microcapillary optics of comparatively small sizes is intended to increase the radiation density, vary the divergence and homogeneity thereof, and construct and rotate beam profiles [7][8][9][10]. New opportunities in principle have appeared because M.A.…”
