This Defense Intelligence Reference Document, prepared in fiscal year 2010 by the Defense Intelligence Agency's Defense Warning Office under the Advanced Aerospace Weapon System Applications (AAWSA) Program, reviews aneutronic fusion as a way to propel spacecraft. It compares chemical, ion, fission, fusion and antimatter propulsion, and it also covers radiation shielding and relativistic rocket calculations. It looks at research needs over the next 30 years for missions from low Earth orbit to Mars, Jupiter and Alpha Centauri.
From the source:Release of 2026-09-18 Incident: 11/1/10, 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 aneutronic fusion as a possible advanced space-propulsion method, focusing on fusion reactions that release most of their energy in charged particles rather than neutrons and therefore offer potential advantages over more neutron-intensive fusion concepts, especially in radiation shielding, direct energy conversion, and thrust generation. The report reviews the underlying rocket physics, compares candidate fusion fuels and ignition conditions, and gives particular attention to proton-boron and related schemes, while also discussing Bussard’s concepts and other fusion projects as representative development paths. It also makes clear that the central obstacle remains ignition and sustained net-energy fusion under practical conditions, and it notes additional problems such as x-ray energy losses from the hot plasma, extreme temperature requirements, and the gap between theoretical specific impulse and what proposed systems had demonstrated experimentally. Overall, the document presents aneutronic fusion propulsion as an attractive long-range concept for deep-space travel, but one whose practical realization still depended on major unresolved advances in fusion engineering.
UNCLASSIFIED//POR. Offl@IAI:: ~S& Qptk\f propulsion has two major hurdles that are currently under investigation at CERN and at the Brookhaven National Laboratory. • Antimatter Generation: Only minute quantities of antimatter have ever been produced. Antiprotons are produced in accelerators and in some radioactive decay schemes. CERN has had an active program since 2000 in antimatter detection and collection. 25 Studies of antimatter production will continue during the upcoming decade due to their importance as a dense storage medium for energy and for their use in particle physics experiments. Current patents should help decrease the costs of production of antihydrogen. Three programs have been part of the CERN Anti matter Factory: - ASACUSA: Antiprotons were directed through helium to generate atoms of helium-2 with antiprotons replacing the orbiting electrons. - ATHENA: An antiproton beam was fired through positrons generated from the decay of Na-22. To generate the antiprotons, a proton synchrotron is used to collide protons on an iridium surface. Antiprotons produced in the collision are directed with electromagnets into an antimatter decelerator and captured. By 2002, ATHENA made 106 antihydrogen atoms in this way. The estimated cost of generating antihydrogen using current technology is about $65 million/gram. - ATRAP: This device used a Penning trap to combine cold antiprotons and positrons to create antihydrogen. • Antimatter Storage: Penning traps and Penning-Malmberg traps have been used to contain antihydrogen for several weeks using a combination of RF and magnetic fields. 26 Further research into antimatter storage will lead to the ability to transport and store nanogram or microgram quantities of antimatter. Speculative Technologies: The Heim Quantum Theory Burkhard Heim was a theoretical physicist that explored a new theory to link quantum mechanics and the Theory of Relativity. 27 He postulated that time and distance are quantized and that matter and energy can be described in terms of 12 dimensions. His worked was followed by the Extended Heim Theory from Walter Droscher and Jochem Hauser. 28 The Heim Theory is able to predict, with a high degree of accuracy, the mass and charge of almost all subatomic particles. New particles, such as the neutral electron, are also predicted. The relationship of his work to space propulsion involves the prediction of a quantum gravity force mediated through graviphotons created from the interaction of matter and virtual particles. Droscher and Hauser have proposed the use of graviphotons to provide propulsion in space with no ejection of matter to generate thrust. There are few peer-reviewed articles on Heim Quantum Theory, and physicists disagree with the formulation of the theory and its results. Nevertheless, this would be the first method that would not require the transfer of momentum by ejecting mass to generate thrust. The Heim Working Group and the work of Drescher and Hauser should be followed for possible application to spacecraft. UNCLASSIFIED/fF&A &FFI&I:.l.k W&& Qptk\f 37
