Concept Studies have shown the IEC to be one of the most attractive approaches to fusion propulsion, provided the physics and technology involved can be scaled-up to high power levels. A key step involves development of a pulsed IEC that can obtain high ion currents along with good ion confinement. Results from initial pulsed IEC experiments are described here. The obtainment of a D-D fusion neutron yield of 8×10[sup 8] n/s at a peak pulse current of 17 A demonstrates that the dynamic formation of the required accelerating fields with the IEC discharge is possible. A next step involves improvement in confinement. © 2000 American Institute of Physics.
