Helicon plasma
Abstract:This thesis analyses the Helicon Injected Inertial Plasma Electrostatic Rocket (HIIPER), a space propulsion concept consisting of a helicon source for plasma generation and an ion extraction method using a nested pair of inertial electrostatic confinement (IEC) grids that are asymmetrically designed. In this study, the HIIPER setup was modelled based on the previous experimental data of the plasma characteristics obtained to account for various power loses and understand the major contributors to the low efficiency and final thrust performance. The loses to the quartz tube wall was substantially higher than the loses at the metal bellow region and the loses due to ionization and excitation. Future improvements in Langmuir probe design to characterize the plasma and the feasible changes to the experimental setup are provided in this study.
