Abstract

Stellarators (“star generators”) belong to the earliest concepts for magneticconfinement of fusion plasmas. In May 1951, a confidential report authored by LymanSpitzer at the Princeton Plasma Physics Laboratory (PPPL) was issued, in which heproposed the “figure eight” stellarator based on the idea to generate the requiredrotational transform of magnetic field lines by twisting the torus into a figure-8.The first experimental device based on this idea started operation in early 1953.In the 1950’s a series of stellarator experiments were built, most of them at PPPL.
