| Description | Journal: Plasma Sources Science and Technology The lowered costs for operational deployment in space, as well as the ability to implement sophisticated peripherals with integrated systems onboard satellites in orbit has catalysed the boom in the space industry. The growth has been driven mainly by the proliferation of minia-turized space systems, which include satellites, rockets and other payloads able to acquire and analyse data in orbit. Of great interest to the community working on the continued miniaturi-zation of satellites and other components for space is the provision of micro-propulsion mod-ules for in-orbit manoeuvres. In this work, we report performance parameters of miniaturized Hall effect plasma thrusters developed at SPC-S, which include thrust, efficiencies, and specif-ic impulse, made possible through a bimodal quadfilar suspended thrust measurement system. Additionally, the plume profiles are studied through a spatially actuated Faraday probe sys-tem. Finally, non-invasive plasma diagnostics through analysis of discharge current oscilla-tions as well as optical emission spectroscopy is presented to give a holistic overview of possi-ble diagnostic methods for real-time measurements pertaining to the evaluation of plasma thruster systems. This work explicitly evaluates the effect of the propellant flow rate on the data obtained through the aforementioned diagnostic methods. |
