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/ /fiOR OfiFl£1.t.k Wli& 8PtLY Detector Array and Analysis System The final imaging quality is determined by neutron source yield integrated over the area of coverage by the number of detectors, the detector configuration, the collimated beam size, the acquisition time, and other scan-related parameters. Scintillators such as Nal, Csl, and BGO as well as Plastic Nal (Tl) are candidates for gamma and x-ray detectors. Due to their small size, they can be used in a large array along with TOF spectrometry to provide detailed special information. Recently, UIUC staff has studied use of an advanced thick Hgb detector which appears to be particularly advantageous for this application. Hgb is a room temperature semiconductor material with an excellent stopping power and a relatively large photo-fraction for detecting high energy gamma rays. Assuming successful development, Hgb detectors would provide superior array performance. With the combined sources, the detector array receives a vast amount of information in a short scan time. To handle this flow of data most efficiently, a fuzzy logic system is employed. The development of this advanced fuzzy !logic system is patterned after a methodology developed for the diagnosis of abnormal situations in nuclear reactor safety analysis. The knowledge box employs a goal tree (and/or decision tree) for representation. This system will use learning -based rules that evolve from extensive simulation tests to provide training about the simultaneous occurrence of specific elements and embedded object shapes. It will also learn to differentiate between positive and negative data by creating rules from these test runs. Materials listed early in the simulation study discussion would be employed. The advantage of this system is twofold . The broad area scan analysis is optimized for fast through-put of objects while the multiple neutron/x-ray identification reduces the probability of false identification. The fuzzy logic system will pass the integrated item or sound an alert (suspicious object in the container) automatically without human involvement. Humans will only be involved when an alert is sounded. An alert occurs for a range of positive identification of materials on to suspected identification . The multiple source detector array concept is designed to minimize items that fall into the category of "in-between" positive identification and clearance. The overall concept described here is illustrated for an airplane luggage scan in Figure 5.3. Data from the detection system (TNA, PFNA and x-ray) is processed through fuzzy logic system. If the item undergoing inspection passes this test, it continues on its way to baggage claim . If an alert is sounded, the item can either be passed through the machine for a second scan or be manually inspected, depending on the confidence level of the alert. Since the integrated system is modular, t he basic components can easily be assembled in a variety of configurations for use at different facilities. An example is the extension to inspection of container ships being unloaded in port as illustrated in Figure 5.4. UNCLASSIFIED/ /fiOA QFFI&IAL WBE 8HLY 52
