“…The theoretical work presented in this contribution applies a radio-frequency (RF) wave-heated (helicon) plasma as an alternative concept for ion sources in various applications [1][2][3][4][5][6][7]. An approximate mathematical model of a helicon type plasma source (coaxial pulsed plasma thruster) was developed and calculation based on the developed multiparameter computational model was previously done.…”

Abstract. The paper presents the results of mathematical modeling of physical processes in electronic devices such as helicon discharge and coaxial pulsed plasma thruster. A mathematical model of coaxial magneto-plasma accelerator (with a preionization helicon discharge), which allows estimating the transformation of one form of energy to another, as well as to evaluate the level of the contribution of different types of energy, the increase in mass of the accelerated plasmoid in the process of changing the speed. Main plasma parameters with experimental data were compared.

“…We apply-for the first time-the ray-tracing technique, extensively used in the laboratory plasma physics [28], to study the effect of general confinement field lines along with typical density profiles on wave propagation and absorption characteristics in plasma sources for space electric propulsion [29]. This approach can be of considerable interest for a large variety of applications including semiconductor manufacturing, material surface modification, material processing, basic and applied laboratory research.…”

Radiofrequency magnetized cylindrical plasma sources are proposed for the development of space thrusters, whose thrust efficiency and specific impulse depend on the power coupled into the plasma. At this stage of research, emphasis has been on the absorption of Whistler wave energy by non-uniform plasmas but not much on the role played by the magneto-static confinement field, considered uniform, constant and aligned with the axis of the source.We present RAYWh (RAY-tracing Whistler), a three-dimensional (3D) ray-tracing solver for electromagnetic propagation and power deposition in cylindrical plasma sources for space plasma thrusters, where actual magnetic confinement configurations along with plasma density profiles are included. The propagation and absorption of Whistler waves are investigated by solving the 3D Maxwell-Vlasov model equations by a Wentzel-Kramers-Brillouin (WKB) asymptotic expansion. The reduced set of equations for the wave phase and for the square amplitude of the electric field is solved numerically by means of a modified Runge-Kutta algorithm.Unexpected cut-offs, resonances, radial reflections, mode conversions and power deposition profile of the excited waves are found, when realistic confinement magnetic fields are considered. An analysis of the influence of axial wavenumbers and the axial length of the system on the power deposition is presented.
