UNCLASSIFIED / SPOR OPTfCEE Sr Ont Inertial Electrostatic Confinement Fusion Preface This report is intended to provide the reader with an overview of the basics, current experimental status, supporting theory, and potential applications of inertial electrostatic confinement (IEC) fusion. Emphasis is placed on work in these areas at the University of Illinois Urbana-Champaign, although some other research is brought in. The report shows that IEC is a unique approach to fusion in that it offers a number of “spin-off” applications, such as a small neutron source for neutron activation analysis o…
