Self-electromagnetic emission from a thruster with anode layer operating with krypton and xenon

Abstract

Abstract This paper considers the study of self electromagnetic emission from the experimental model of low-power thruster with anode layer (TAL) developed by the Bauman Moscow State Technical University. The measurements were carried out during the thruster operation on krypton and xenon for three operating modes: 600 W, 800 W and 1000 W at a discharge voltage of 300 V. Parameters of the generated electromagnetic fields were measured in frequency range from 1 GHz to 12 GHz in the filter bandwidth of 1 MHz. The receiving antenna was installed at a distance of 1 m from the thruster exit plane, perpendicularly to its axis. The results of analysis and comparison of TAL emission spectral characteristics during its operation on krypton and xenon are presented.
