"The QED Engine System: Direct Electric Fusion-Powered Systems for
Aerospace Flight Propulsion" by Robert W. Bussard, EMC2-1190-03,
available from Energy/Matter Conversion Corp., 9100 A. Center
Street, Manassas, VA 22110.
[This is an introduction to the application of Bussard's version
of the Farnsworth/Hirsch electrostatic confinement fusion
technology to propulsion. 1500<Isp<5000 sec. Farnsworth/Hirsch
demonstrated a 10**10 neutron flux with their device back in
1969 but it was dropped when panic ensued over the surprising
stability of the Soviet Tokamak. Hirsch, responsible for the
panic, has recently recanted and is back working on QED. -- Jim

"PLASMAKtm Star Power for Energy Intensive Space Applications", by
Paul M. Koloc, Eight ANS Topical Meeting on Technology of Fusion
Energy, special issue FUSION TECHNOLOGY, March 1989.
Aneutronic energy (fusion with little or negligible neutron
flux) requires plasma pressures and stable confinement times
larger than can be delivered by current approaches. If plasma
pressures appropriate to burn times on the order of milliseconds
could be achieved in aneutronic fuels, then high power densities
and very compact, realtively clean burning engines for space and
other special applications would be at hand. The PLASMAKtm
innovation will make this possible; its unique pressure
efficient structure, exceptional stability, fluid-mechanically
compressible Mantle and direct inductive MHD electric power
conversion advantages are described. Peak burn densities of tens
of megawats per cc give it compactness even in the
multi-gigawatt electric output size. Engineering advantages
indicate a rapid development schedule at very modest cost. [I
strongly recommend that people take this guy seriously. Bob
Hirsch, the primary proponent of the Tokamak, has recently
declared Koloc's PLASMAKtm precursor, the spheromak, to be one
of 3 promising fusion technologies that should be pursued rather
than Tokamak. Aside from the preceeding appeal to authority, the
PLASMAKtm looks like it finally models ball-lightning with solid
MHD physics. -- Jim Bowery]
Retrieve files pub/SPACE/SPACELINK/6.5.2.* from the Ames SPACE
archive; these deal with many aspects of ion drives and describe the
SERT I and II missions, which flight-tested cesium ion thrusters in
the 1960s and 70s. There are numerous references.
IEEE Transactions on Magnetics (for example, v. 27 no. 1, January
1991 issue). Every so often they publish the proceedings of the
Symposium on Electromagnetic Launcher Technology, including hundreds
of papers on the subject. It's a good look at the state of the art,
though perhaps not a good tutorial for beginners. Anybody know some
good review papers?

"Alternate Propulsion Energy Sources", Robert Forward
NTIS AD-B088 771/1 PC A07/MF A01 Dec 83 138p
Keywords: Propulsion energy, metastable helium, free-radical
hydrogen, solar pumped (sic) plasmas, antiproton annihiliation,
ionospheric lasers, solar sails, perforated sails, microwave
sails, quantum fluctuations, antimatter rockets... It's a wide,
if not deep, look at exotic energy sources which might be useful
for space propulsion. It also considers various kinds of laser
propulsion, metallic hydrogen, tethers, and unconventional
nuclear propulsion. The bibliographic information, pointing to
the research on all this stuff, belongs on every daydreamer's
shelf.
