This Defense Intelligence Reference Document, dated 10 March 2010, was prepared by the Defense Intelligence Agency's Defense Warning Office under the Advanced Aerospace Weapon System Applications Program. It surveys the basics, experimental status, theory and possible uses of inertial electrostatic confinement (IEC) fusion, with emphasis on work at the University of Illinois Urbana-Champaign. It covers neutron sources, explosives detection and space propulsion. It ends by proposing a 12-gun hydrogen plasma experiment meant to show breakeven conditions for p-11B fuel.
From the source:Release of 2026-09-18 Incident: 3/10/10, Las Vegas, Nevada. Released with redactions. This document is a Defense Intelligence Reference Document (DIRD), a technical reference format used by the Defense Intelligence Agency (DIA) to capture baseline knowledge on a specific topic for later analytic use. DIRDs are best understood as reference and synthesis products rather than as original research. It is one of 38 DIRDs produced under the Advanced Aerospace Weapon System Applications Program (AAWSAP) between 2009 and 2011. Because AAWSAP’s scope permitted a broad range of supporting topics, not every DIRD in the series directly concerns aerospace systems or future threat assessment. The following summary reflects the DIRD’s scope and framing at the time of writing and should not be read as implying current validation of the concepts discussed. This DIRD surveys inertial electrostatic confinement (IEC) fusion, a relatively unconventional fusion concept that uses electric fields rather than the more established magnetic or laser-based approaches to confine ions, and it reviews both the underlying physics and the experimental work associated with the concept. The report emphasizes that IEC may have nearer-term value as a compact neutron, proton, or x-ray source and as a platform for studying experimental fusion approaches, while also presenting more ambitious possibilities such as aneutronic power generation and propulsion applications. At the same time, it makes clear that the concept remained far from practical fusion power, with experimental devices operating several orders of magnitude below breakeven and with major unresolved issues involving confinement, losses, grid damage, and scale-up. Overall, the document treats IEC as a technically interesting but still highly speculative path toward fusion energy, while suggesting that its more limited spin-off applications were more plausible in the near term than its long-range power generation or propulsion applications.

Section VI. Possible Next Step Breakeven Experiment The prior sections have presented much information about the existing data base and theory for IEC operation. The potential for use in applications such as a neutron source and related radiation sources (proton and x-ray) are well established. However the ultimate goal is to develop a power-producing IEC. Better yet to do this taking advantage of the unique ability of the IEC to use non -Maxwellian plasma to burn advanced fuels to minimize radioactive and radiation emission involvement. However the best current device resu lts are 5 or 6 orders of magnitude down in energy gain Q (energy out/ in) from breakeven. Thus it may appear that such a hope is many years off. Fortunately, the IEC can be scaled up in energy gain while keeping a small size since the losses are in velocity space (i.e. via ion upscattering out of the potential well trap). This is in sharp contrast to Tokomaks where loses occur via diffusion across the outer surface, so Increased confinement times have been achieved by going to the massively large ITER type devices. The problems and costs for construction of ITER have thrown its development in to the distant future, making this approach ineffective for addressing the present energy crisis (or as a LLNL associate director recently bemoaned, "Fusion is irrelevant- no politicians even mention it In the energy scenario"). To provide the reader with some insight into the IEC "vision" for power, we next present a conceptual proposal for a near term IEC breakeven experiment to prove the physics of operation with aneutronic p- 11 B fuel. If such a program can be initiated aggressively, the IEC cou ld have a major impact on the energy crises . DEMONSTRATION OF NET ENERGY GAIN USING IEC ANEUTRONIC FUSION The IEC is one of the few approaches to fusion that has the potential of burning aneutronic fuels such as D- 3He and p- 11B in a reasonable scale device. This fue l results in charged-particle reaction products wh ich allow efficient use of direct energy conversion technology with no direct greenhouse emissions and minimal radioactivity or radioactive wastes. Such a power source has all of t he features sought for future power plants needed worldwide to turn the tide of the growing energy crisis. The experiment proposed here would provide verifiable and reproducible proof of break-even conditions necessary to burn p- 11 B as a practical aneutronic fuel in an IEC fusion power-generating device.
