Design considerations for a migma advanced fuel fusion reactor

The migma concept is being pursued at Fusion Energy Corporation as a means of achieving controlled fusion. The features which distinguish this concept from other controlled fusion concepts may be summarized as: (1) high energy; (2) ordered motion; (3) use of advanced fuels; and (4) small physical size. Beams of ions are injected into the field of a superconducting magnet at MeV energies. The resulting motions of trapped ions have a high degree of order in phase space compared with a thermalized gas. At MeV energies the two major ion loss mechanisms, charge transfer and multiple Coulomb scattering, are greatly suppressed compared with thermonuclear energies (1 to 100 kev) because the cross section for multiple Coulomb scattering falls off as T-1.5 and that for charge transfer approximately as T-5
