Helicon Source for Ion Propulsion
Electric thrusters are usually in one of two forms: gridded ion thrusters or Hall thrusters. Each of these accelerates ions and requires an injector of electrons to neutralize the ion beam. Ambipolar thrusters eject neutralized plasmas with equal numbers of ions and electrons. Helicon thrusters are a new type being developed which utilize both the high ionization efficiency of magnetized helico...
متن کاملStrong ion-sound parametric turbulence and anomalous anisotropic plasma heating in helicon plasma sources
Experimentally observed anisotropic ion heating in helicon plasma sources may result from the interaction of ions with ion-sound turbulence. The ion-sound turbulence develops due to excitation of the short scale, kinetic, parametric ion-sound instability. From the quasilinear equation for the ion distribution function, which includes the induced scattering of ion-sound waves by ions, the turbul...
متن کاملRF absorption and ion heating in helicon sources.
Experimental data are presented that are consistent with the hypothesis that anomalous rf absorption in helicon sources is due to electron scattering arising from parametrically driven ion-acoustic waves downstream from the antenna. Also presented are ion temperature measurements demonstrating anisotropic heating (T( perpendicular)>T(parallel)) at the edge of the discharge. The most likely expl...
متن کاملThrust Measurements of a Helicon Plasma Source
There is interest in using a helicon plasma source in propulsive applications as both an ion source and as a thruster. Developing a helicon thruster requires a performance baseline as a basis for future optimization and expansion. The thrust of a helicon is measured using an null-type inverted pendulum thrust stand at a pressure of 2x10 -5 Torr through the operating range of 215-840 W RF power,...
