【 摘 要 】

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 selforganisation, driven by DC edge currents, provides the means by which toroidal current becomes driven. The benefits of this engineering simplicity would be realised 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 B-limited discharges were all observed in CTX and subsequent theoretical studies pointed to the presence of good coreconfinement during the decay phase.
