OTHER CONCEPTS

There are concepts under study that cannot be categorized in the externally controlled/self-organized scheme. Two examples are magnetized target fusion and the dipole configuration. Magnetized target fusion compresses a compact toroid to densities intermediate between those of magnetically and inertially confined plasmas. It offers a new, perhaps simpler approach to fusion, as well as access to plasma physics regimes. The dipole configuration mimics confinement of plasma in planetary magnetospheres, again offering special advantages and physics insights.
