Stellarators with the magnetic symmetry of a tokamak

To meet the requirements of the U.S. Stellarator Power Plant Study, a Modular Helias-like Heliac (MHH) configuration was developed that has features in common with a quasihelically symmetric experiment proposed at the University of Wisconsin [D. Anderson and P. Garabedian, Nucl. Fusion {bold 34}, 881 (1994)]. Improvements have been made in the design of the MHH that raise the {beta} limit, increase the confinement time, and simplify the geometry of the coils. In particular, specifications have been found for a stellarator with just two field periods that has a magnetic field spectrum {ital B}{sub {ital mn}} close to axial symmetry. This configuration has physical properties that make it an interesting candidate for a follow-on experiment to assess the equilibrium, stability and transport of advanced stellarators. {copyright} {ital 1996 American Institute of Physics.}
