Abstract
The generation of a low-frequency low-pressure inductive discharge with ferromagnetic enhancement of the magnetic coupling between the coil and the plasma is investigated. The main features and advantages of this plasma generation method for surface processing technologies are considered. New experimental data on the electrophysical and dynamic characteristics of ferromagnetic-enhanced low-pressure inductive discharge in argon with the addition of oxygen are presented. It is shown that the radial distribution of plasma parameters in a gas-discharge chamber can be controlled using distributed discharge generation. Significant fluctuations in the electron temperature during the discharge electric field period are found, and the mechanism of their occurrence is analyzed.
