Device for stable plasma confinement by cross-helicity generation at the Alfvén velocity

A new device configuration is described to stably confine plasma. Helical fluid flow driven at the Alfvén velocity by spatially-periodic cusped magnetic fields and edge currents is combined with magnetic helicity injection to generate the conserved quantity of cross-helicity for the formation of a stable Taylor-Couette-like magnetohydrodynamic singular structure. The basic outline of the device is shown, its nominal use case being for generating fusion power, and to further illustrate the generality of cross-helicity generation, a laminar kinematic dynamo generator is also shown.
