A newcomer: the Wendelstein 7-X Stellarator
Stellarators (“star generators”) belong to the earliest concepts for magnetic confinement of fusion plasmas. In May 1951, a confidential report authored by Lyman Spitzer at the Princeton Plasma Physics Laboratory (PPPL) was issued, in which he proposed the “figure eight” stellarator based on the idea to generate the required rotational 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.
