The Simple Axisymmetric Mirror A Physics & Engineering Game Changer
• Simple magnet geometry stabilized by plasma exhaust– Physics established: Novosibirsk GDT Device – 60% beta, Te, classical– Extrapolates to a Dynamic Trap D-T Neutron Source (DTNS)– ~ 2 MW/m2 Neutron Flux, ~2 m2 Area, ~100 Liter Volume– Simple Geometry, Ease of Construction & Maintenance– Addresses Greenwald Gaps 10 & 13 and Initiative 7 Neutron Source

GDT at Novosibirsk, Russia12 m Long with Large End Tanks to Decouple Te
One Version of DTNS Showing Magnets, Shielding ,Neutral Beams, and Material Samples
(Bobouch, Fusion Science & Tech. 41 (2002) p44)
Neutron Flux Scales With Te to 4 MW/m2(for various NBI energies)
DTNS Could Produce ITER-Like Neutron Energy Spectra
• DTNS Physics Has Much in Common with Other Confinement Systems
• Tests Existing Modeling Capability in Very Simple Geometry
• More Efficient DTNS (end cells) Leads to a Fusion-Fission Hybrid
• Benefits Outside Magnetic Fusion
• Fosters International Collaboration
