Abstract: HT4.00101 : Density profile control of a magnetically expanding plasma and its impact on a plasma thruster*
In this study, it is demonstrated that the radial density profile in the magnetic nozzle rf plasma thruster can be controlled by adjusting the rf powers to two rf antennas wound around the source tube. In addition, the thrust component corresponding to the Lorentz force onto the magnetic nozzle is solely measured to clarify the impact of the density profile on the imparted thrust. The results show the controllability of the density profile of the ICP in the magnetic nozzle and indicates the possible impact of the density profile on the thrust.
