A D-H sub e sup 3 Fusion Reactor Based on Dipole Magnetic Field

An innovative fusion reactor suitable for D-H sub e sup 3 fuel is proposed based on a dipole magnetic field producted by a simple one turn coil with ~16 tau near field intensity. The equilibrium plasma whose phase space density satisfies partial f sub o (mu,J,Psi)/partial Psi = 0, where partial is the flux function, has a steep enough pressure profile for an efficient fusion reaction yet is stable for low frequency instabilities to local beta exceeding unity. The semi-open field configuration is particularly suitable for D-He sup 3 reactions.
