Electron beam machines with the plasma cathode guns are presented. All machines possess high extent of automation. The high-voltage source has effective protection against breakdowns and small time of restoration. Machines are equipped ...read more
Electron-optical characteristics of electron beams generated in sources of two types are considered. One of these sources is based on reflected hollow cathode discharge and the other one rests on a modified reflected discharge. They ...read more
The work is devoted to exploring the determining possibilities of the high-power technology electron beams parameters by the beam glow image on the residual gases in the vacuum chamber. Digital camera is used to make images in the visible spectrum.
In this article defining of the time of current increasing in triode high voltage glow discharge electron guns for investigation its technological possibilities is considered. Provided analyse is based on calculation the parameters ...read more
A plasma cathode electron beam (EB) gun is presented in this work. A radio frequency (RF) excited plasma at 84 MHz was used as the electron source to produce a beam power of up to 3.2 kW at -60 kV accelerating voltage. The pressure ...read more
The paper is devoted to electron beam guns based on the emission of electrons from plasma of a hollow-cathode reflective discharge. The measuring of the diameter and brightness of beam with the rotating wire sensor and scanning slit ...read more
In previous period it was created a method of improving corrosion resistance of construction steel tubes situated in liquid heavy metal coolants (as example Pb and Pb-Bi used in nuclear reactors). At beginning on the steel surface is ...read more
Electron beam surface treatment and 3D printing impose stringent beam deflection requirements. The deflection must be of high frequency (some 50 kHz), high amplitude (10 s of μm) and accurate (to within 10 microns). Methods are described ...read more
