Abstract
The article presents the results of a study examining the influence of microwave electromagnetic energy on the low-frequency component of a combined (microwave and low-frequency) discharge plasma. The output electrical parameters of a low-frequency generator and the optical characteristics of a combined medium-vacuum discharge plasma were experimentally studied. It was determined that, during the generation of a discharge formed by the simultaneous action of microwave and low-frequency fields in a single discharge volume at a pressure of 20–100 Pa, a constriction effect of the low-frequency component of the combined discharge may occur. This effect consists of a change in the current transfer conditions in the plasma layer between the electrodes under the influence of a magnetic field, which leads to a decrease in the amplitude of the low-frequency generator output voltage. The dependence of the change in the voltage amplitude of the low-frequency generator on the output power of the microwave generator power source was established.
