Abstract: A continuous electrode (CE) inertial electrostatic confinement (IEC) device has particle paths radially extending from a central core region. Each particle path has a corresponding particle path aligned on an opposite side of the central core region. Sidewalls bounding the particle paths provide continuous surfaces radially extending from a cathode region proximal to the central core region to an anode region remote from the central core region. Electrodes are coupled to the sidewalls to provide an electric field that varies along each particle path from the cathode region to the anode region. The CE-IEC device can be used for particle fusion by directing ions along the particle paths to the central core region, for example, to generate power or to propel a spacecraft.
