Title: Sustainment of a Spheromak by DC Helicity Injection

Abstract

A spheromak fusion reactor would be simple and inexpensive, and might actually work. The absence of both toroidal field coil windings and central-column stack reduces complexity and means that the toroidal plasma will be simply connected and compact. Intrinsic self-organization, driven by DC edge currents, provides the means by which toroidal current becomes driven. The benefits of this engineering simplicity would be realized in the ultimate cost of a reactor. Previous spheromak experiments have produced good confinement with a simple design. 1MA toroidal currents, hard X-rays and {beta}-limited discharges were all observed in CTX and subsequent theoretical studies pointed to the presence of good core-confinement during the decay phase.
