Abstract:

Cuspher is a magnetic confinement system which combines a closed [spheromak] and an open [cusp] system. The open system surrounds the closed system that provides a plasma reservoir. The closed system is assumed to have gross mhd stability but is not required to have plasma particle and energy confinement. The overall confinement is determined by the convective plasma loss from the open system and the volume of the closed system. The fusion condition may be attained in a relatively modest size device.
