A NEW PLASMA CONFINEMENT GEOMETRY
S>The picket fence or cusped geometry method of plasma confinement is discussed with reference to a new geometry based on the helix and called the helixion. which makes possible stable beta = 8 pi nkT/B/sup 2/ = 1 confinement with zero cusp losses in a torus. The problem of maintaining hydromagnetic stability in the bridge between the cusps on either side of the helixion wire is treated. The heiixion idea is extended to an open-ended helixion. It is stated that as the inclination of the wire to the magnetic field is reduced, the cusped region shrinks and vanishes without touching the wire. The advantages of an open- ended helixion are that it is easier to cool the helix and to operate it on the d- c. The magnetic lines also can be terminated at the ends, thereby making it possible to divert the quiescent plasma diffusion to the walls. (D. L.C.)
