Effect of control of a fast-electron beam using a ceramic channel

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 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 demonstrate

Study of the transmission of 10-keV electrons through a ceramic macrochannel

Transmission of 10-keV electrons through a ceramic macrocapillary in the geometry, where the channel axis is oriented parallel to the incident-beam axis, has been studied experimentally. The current and energy spectrum of electrons passing through the channel have been measured depending on the incident beam current and the channel irradiation tim

10-keV electrons transmission through a set of dielectric macrochannels

The results of the study of the 10-keV electron beam transmission through cylindrical dielectric macrochannels with various lengths. All channels made of polyethylene terephthalate had an identical inner diameter of 1.55 mm and lengths of 20, 30, 35, 40, 45, and 50 mm. The dependence of the current passed through beam channels on their tilt angle relative to the incident electron beam is measure
