The possibility of controlling charged-particle beams by the use of dielectric channels (guiding) is an urgent task because of the potential of developing inexpensive autonomous controlling and focusing devices. At present, experiments with the use of ions with an energy on the order of MeV are intended for the application of radiation with a spot size of about one micrometer for material analysis, surface modification, and cell surgery. In the case of using electron beams, such a possibility is still under study. In this work, the possibility of controlling a beam of accelerated electrons by using a ceramic channel in the case of its inclination both in the vertical and in horizontal planes is demonstrated. Data about the control are obtained for the channel after irradiation of both its end faces for no less than 5 h. After such treatment, an inhomogeneous carbon-containing deposit is formed on the interior surface of the channel near its end faces. It is demonstrated that the formed deposit has no influence on the guiding properties of the channel.
