Attribute Value
Methodology
  • - Diagnostic data taken for the PEPL RMFv2 Rotating Magnetic Field Thruster operating at 4.0 mg/s xenon flow, 2000 A pk-pk RMF currents, 180 G centerline magnetic field strength and 125 us pulse duration - Data included: far field guarded Faraday probe, antenna current waveforms, thrust results, and spatial triple Langmuir probe. - Data collected at the University of Michigan Plasmadynamics and Electric Propulsion Lab (PEPL) during the spring of 2022.
Description
  • Rotating Magnetic Field (RMF) thrusters are a form of electrodeless plasma propulsion. This technology is a low maturity but potentially enabling candidate for high-power in-space propulsion for use with alternative propellants. The purpose of the data here, and the associated publication is to evaluate the phenomenological efficiency modes for this thruster test article to explain and understand its overall efficiency. These modes include divergence, power coupling, mass utilization, and plasma/acceleration efficiency. Additional time-resolved measurements of the internal plasma properties were performed using a triple Langmuir probe to evaluate energy loss processes within the thruster.

Research Overview:
Rotating Magnetic Field (RMF) thrusters are a form of electrodeless plasma propulsion. This technology is a low maturity but potentially enabling candidate for high-power in-space propulsion for use with alternative propellants. \
The purpose of the data here, and the associated publication is to evaluate the phenomenological efficiency modes for this thruster test article to explain and understand its overall efficiency.
These modes include divergence, power coupling, mass utilization, and plasma/acceleration efficiency.
Additional time-resolved measurements of the internal plasma properties were performed using a triple Langmuir probe to evaluate energy loss processes within the thruster.
