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.
UNCLASSIFIED/ /POI\ OPPICllct tt!I!! 9HLY The three detection techn iques shown in Table 5.1 have previously been used independently in inspection units. The present integrated unit makes use of all three simultaneously. Thus, the strengths of each device combine to provide consistent overall coverage of elements/objects. Table 5.1.

The 14. 1-MeV neutrons from the D-T reaction will be the primary source for TOF FNA wh ile thermalized neutrons from a block of neutron thermalizing plastic in front of the 2.45-MeV DD IEC will be used for TNA. This combination will increase spatial resolution and significantly reduce the false allarm rate to a low level compared to conventional methods which emp loy single sources and are li mited to yield due to lack of broad area sources. Overview for Weapons/Nuclear Material Simulation Articles The following three categories of items provide a overview of articles of interest for detection in inspection stations. A. Explosives which are of high O and N, low C and H elementa l densities are listed below with sizes ranging from 8 x 8 x 8 cm 3 to 20 x 20 x 20 cm 3 . • RDX (Cyclonite , C3HGNGO6) with p = 1.83 g/cm 3. • TNT(Trinitrotoluene, C7HsNJO6) with p = 1.654 g/cm 3 . • PETN(Penthrite, CsHsN4O1 2) with p = 1.773 g/cm 3. • TATB(Triaminotrinitrobenzene, CGHGNGOG) with p = 1.93 g/cm 3• UNCLASSIFIED/ /FOR 8FFl€i1Ak W&lii 0NkY 48
