Magnetic fusion with high energy self-colliding ion beams

Self-consistent equilibria are obtained for high beta plasma where almost all of the ions are energetic with a gyroradius of the order of the plasma scale length. Magnetohydrodynamics would not apply to such a plasma. Recent experiments with tokamaks suggest that it would be insensitive to microinstabilities. Several methods are described for creating the plasma with intense neutralized ion beams.
