Effects of Helicon Wave Propagation Based on a Conical Antenna Design: Part I (Preprint)

Abstract

An annular field reversed configuration (FRC) plasma concept is being developed by the University of Michigan and AFRL to investigate inductively-coupled high power electric propulsion. Presented is the continued exploration of an annular FRC with specific focus on main bank discharges, magnetized plasma toroid formation, and preliminary investigation into plasma translation. Additional detail is given towards discharge parameter space, optimization of energy input/translation, and predictive scaling laws of magnetic flux, plasma density, and plasma energy content. The discharge parameter space covers multiple charging energies, voltages, and timing as well as multiple propellants and pre-ionization techniques. Finally, a case for FRC formation is made by investigating magnetic field (and flux) reversal in the coil as well as downstream magnetic field modification by a high density magnetized plasma.
