Interests
Dr. King
is an experimentalist interested in studying electric space propulsion
systems, including Hall-effect thrusters, ion engines, and arcjets. By
utilizing strong electromagnetic forces to accelerate an ionized plasma
propellant, electric thrusters take advantage of on-orbit solar power generation
to enjoy significant fuel savings over traditional chemical rockets. King's
research experience in the broader field of plasma physics includes such
diverse subjects as the design of the in-situ electrostatic probes, ion-energy
analysis and time-of-flight mass spectrometry, Doppler laser cooling of
trapped ions, optical flow diagnostics, and antimatter confinement.
