High Efficiency RF Heating for Small Nuclear Fusion Rocket Engines, Phase I

Metadata Updated: May 2, 2019

High power nuclear fusion propulsion systems will require high efficiency radio-frequency heating systems in the MHz range for plasma heating. This proposal is for a novel scalable solid state Class E amplifier using Silicon Carbide switching transistors for plasma heating. This system is potentially 100% efficient compared to 40% for linear amplifiers and can be scaled to any desired size by adding additional segments in parallel. The system includes a novel closed loop feedback control system at the antenna and from the plasma. This eliminates the need for lossy transformers and other non-ideal components. The RF amplifier will be prototyped in Phase I in preparation for a plasma heating experiment in Phase II.
