Abstract
There is an urgent need for small power units for on-board and landing site power for space travel. The conceptual design of a 1-MWe Inertial Electrostatic Confinement (IEC) fusion unit burning D-3He fuel is considered here for such applications. The IEC is attractive for space power—its non-Maxwellian beam-beam character is well-suited for D-3He operation, small size units with a high specific power density are conceivable. Small scale IEC experiments have produced encouraging results and are used here as the basis for extrapolation to the space power unit. However, critical scale-up experiments are essential to verify the feasibility of the concept.There is an urgent need for small power units for on-board and landing site power for space travel.
