Control of electron, ion and neutral heating in a radio-frequency electrothermal microthruster via dual-frequency voltage waveforms

Doyle, Scott J; Gibson, Andrew R; Boswell, Roderick; Charles, Christine; Dedrick, James


The development of low power micro-propulsion sources is of recent interest for application on miniature satellite platforms. Radio-frequency. (rf) plasma electrothermal microthrusters can operate without a space-charge neutralizer and provide increased control of spatiotemporal power deposition. Further understanding of how the phase-resolved rf plasma heating mechanisms affect the phase-averaged bulk plasma properties, e.g. neutral gas temperature, could allow for in-flight tailoring of...[Show more]
