Stellarator-spheromak (SSP) is a magnetic confinement
concept where external windings are used to produce stellarator effects in a
spheromak-like configuration. The regime of high plasma pressure (high beta)
operation is critically important for the SSP because of importance of internal
plasma currents (which are larger at higher plasma pressure). The SSP approach
remains main advantages of spheromaks, such as compact design and absence of
material structures in the center of the torus, and has a potential to improve
the traditional spheromak concept regarding its main problems related to
difficulty of reaching steady-state operation and avoiding the fast-growing
tilt/shift plasma instability. Stellarator-spheromak was discovered as an
interesting and novel approach during author's research on
spherical stellarators. It's unfortunate that without
financial support the SSP concept is not currently under development.
