High Power LaB$_{\mathrm{6}}$ Plasma Source Performance for the Lockheed Martin Compact Fusion Reactor Experiment

Lockheed Martin's Compact Fusion Reactor (CFR) concept is a linear encapsulated ring cusp. Due to the complex field geometry, plasma injection into the device requires careful consideration. A high power thermionic plasma source (\textgreater 0.25MW; \textgreater 10A/cm$^{\mathrm{2}})$ has been developed with consideration to phase space for optimal coupling. We present the performance of the plasma source, comparison with alternative plasma sources, and plasma coupling with the CFR field configuration. \copyright 2016 Lockheed Martin Corporation.
