The orientation effects during the grazing interaction of fast electrons with structured surfaces

Abstract

Background/Objectives: The paper presents the experimental results of a study of the processes of grazing interaction of fast charged particles with structured surfaces. Methods/Statistical analysis: The experiments performed to study the radiation arising when the electrons pass along a structural surface are carried within a small angle region. According to the results presented in Figure 4 the maximum of electrons lifting can be observed at angles close to 1°-2°. So it will be necessary to use different grounding schemes to improve the yield efficiency. This can be achieved when both sides are grounded. Findings: The contribution of the structure of the target surface to the scattering of the incidence primary electrons was observed for different geometries for the interaction process of a 10keV electron beam with a diffraction grating. The experimental results demonstrate the possibility of increasing the total time of the interaction between the electron beam and the target, which opens the possibility to increase the effectiveness of radiation sources, based on diffraction mechanisms. Applications/Improvements: The effect of contactless transmission of electrons through dielectric channels causes great attention because of the potential use of simple and independent systems for electron beams formation.
