Investigation of the guiding effect of 10-keV electrons using planar dielectric surfaces

The effect of guiding a 10-keV electron beam using dielectric plates is studied. It is shown that the electron beam after interaction with the insulator surface is deflected by this surface in different ways depending on a variety of grounding schemes of the front and back sides of plexiglass and aluminum-oxide plates. The dependence of the deflection of the beam from the plexiglass plates at different angle positions on the incident electron-beam current value is studied.
