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.
UNCLASSIFIED//FIHl 8FFHil.t.k Wfili 8Hklf The three detection techniques 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. Three Kinds of Techniques Previously Used in Explosives Detection System Here, TNA and FNA represent thermal and fast neutron activation, respectively. TNA FNA X-ray Element Identification Element Density Nitrogen High Medium - Carbon Very Low Very High - Oxygen NA Iligh - Hydrogen Very High High - Chlorine Very High High - C/0 Ratio NA High - Background Noise High Low NA Imaging: geometry & localization Pulsed FNA Limited provides depth High resolution information information Suitcase to Suitcase to cargo, Application Small suitcase not good for cargo plastics ohjects Cunfiguraliun CurnplicatcJ Cumplicatcd Simple Operation & Maintenance Cost High High Low The integrated IEC system employs a combination of PFNA/TNA methods and conventional x-ray techniques to collect elemental information as well as a 3-D imaging of any suspected objects. The 14.1-MeV neutrons from the D-T reaction will be the primary source for TOF FNA while 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 alarm rate to a low level compared to conventional methods which employ single sources and are limited 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 D and N, low C and H elemental 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, C3H6N6O6) with p = 1.83 g/cm 3 . • TNT(Trinitrotoluene, C1HsNJO6) with p = 1.654 g/cm 3 . • PETN(Penthrite, CsHsN4O12) with p = 1.773 g/cm3. • TATB(Triaminotrinitrobenzene, C5H 6N6O6 ) with p = 1.93 g/cm3. 48 UNCLASSIFIED/ /Pett errI@ItllL ~:!II!! 8HLV
