larger nuclear fusion space propulsion program. I will pull out the specific research progress that was reviewed by George Miley. A lot of it is work done at the University of Illinois where George leads a nuclear fusion research lab.
Other IEC Fusion configurations and approaches
MSCA = linked IECs (discussed later for high power units)
A 7 page paper- Magnetically-Channeled SIEC Array (MCSA) Fusion Device for Interplanetary Missions
Dipole Assisted Fusion
Cylindrical IEC Fusion
Less convergence than spherical – reduced fusion rate, but large volume along axis gives large total yield.
Very useful for certain practical applications, for example:
Broad area scans for HS inspections
Insertion into cylindrical fuel element slot in fission systems for drive sub-crical operation
Current Worldwide efforts on IEC fusion:
U of IL – G. Miley, et al.
U of Wisc – J. Kulciniski, et al.
MIT – R. Sedwich, et al.
U Mo – M. Prelas, et al.
LANL and EMC2 – R. Nebel, et al.
Japan – Kyoto – M Ohnishi, et al.
Australia – U Sydney – Joe Kenney, et al.
UNSW – H. Hora, et al.
The Star mode neutron generator was commercialized by Daimler-Benz. It generates ten million neutrons per second.
IEC fusion for space
Components have been studied experimentally. Ion Injection. Collimation and direct convertor.
Near Term -The IEC Has Been Investigated as a Propulsion Unit Operating in “Jet Mode. Estimated Performance: T = 34 mN, Isp = 3000 s, Accelerating Potential: 600 V Input Power ~750-800 W, Pjet = 500 W, ht ~ 62-68%
