Defense Intelligence Reference Document Inertial Electrostatic Confinement Fusion

Defense Intelligence Agency · 72 pages · text from the file's own layer

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.

are possible in Penning IEC devices provided that: 1) The electrostatic well is deep
enough (Eo > 100 kV); 2) Ion confinement time is long enough ( 9 > 0.01); and 3) Ion
source strength is moderate (Smax 100
have been identified, as plotted in Figure 4.3. These results ignore electron
Bremsstrahlung loss however. That effect on the Q-value was addressed heuristically by
Chacon using a semi-analytic model, indicating that quite large Q-values are still
possible, provided that electron particle losses are kept small and well depths are large.
These results show that in addition to potential well shape, the source strength vs. up-
scattering losses plays a crucial role in the IEC energy gain. More insight into this can
be obtained from the distribution functions for trapped ions, sketched in Figure 4.3.
