This Defense Intelligence Agency reference document, dated 10 March 2010, covers inertial electrostatic confinement (IEC) fusion. It was produced in FY 2009 under the DIA's Advanced Aerospace Weapon System Applications (AAWSA) program. The report focuses on work at the University of Illinois Urbana-Champaign and reviews IEC basics, experiments, theory and applications such as neutron sources, explosives detection and space propulsion. It concludes by proposing a breakeven experiment for p-11B fusion that uses a hydrogen plasma simulation.

Plot of the Q-value (including electron losses) as a Function of (a) Sma, and y with fe= 10·3 , (b) Smax and fe with y =5, (c) Sma. and fe with y =100, and (d) Smax and Eo with y= 5 and fe =10-3 • These plots have been obtained for Eo =100 keV [except (d)], 9b =0.01, and E, =l.04. (Nomenclature is defined in Reference 4.2). The source to sink issue noted several times here can be explained as follows. Two opposite limits of this kind of solution are depicted in Figure 4.4. The realization of either of these limits depends on the equilibrium between two competing effects, namely up-scattering of the Maxwellian ion component confined in the well (which increases as the Maxwellian temperature increases and tends to empty the well), and down-scattering of the beam (which tends to fill it). The relative importance of these effects is directly related to the strength relatives of the source and the sink. They are characterized here by Smax = maximum value of the ion source, and t = ion replacement time, respectively. Thus, weak sinks and strong sources will result in a large beam population, increasing the beam down-scattering rate and hence increasing "effective" Maxwellian temperature, given in the dotted line profile in Figure 4.4. Conversely, weak sources and strong sinks will result in a small beam population, thus decreasing the beam down-scattering rate and resulting in lower Maxwellian temperatures, leading to the solid line profile in Figure 4.4. 37 UNCLASSIFIED//FQA: QFFI&lal k I l&'i Qllk¥
