Description
Since the introduction of the term "helicon" scientific community's interest in this phenomenon grew. Currently, several international groups conducted a number of large-scale experiments in this field of plasma physics [1-9]. These studies have shown that the installations based on helicon discharge are very attractive as a source of high density plasma due to the large resource exploitation.
The use of helicon sources in the technologies deposition will significantly reduce the cost of equipment maintenance, in the absence of its erosion. However, it is necessary to determine the qualitative component of the considered technology of ions deposited substances.
This paper presents the results of a study of the empirical dependence of plasma parameters (degree of ionization, plasma density, temperature) from the input parameters (power, frequency, current, magnetic induction) using a number of azimuthally asymmetric antennas for the helicon plasma source used ionization of Tungsten (W), Molybdenum (Mo) and Titanium (Ti). Different antenna configurations for helicon source are considered and compared. Use of a helicon discharge as the plasma source for a plasma-based space thruster is discussed.
