levitron Physics.|ˈlɛvɪtrɒn|
[f. levitate v. + -tron.]
A type of fusion reactor in which stability of the plasma inside a toroidal container is achieved by the combination of a magnetic field parallel to the sides of the torus, produced by an external winding, with a second field everywhere at right angles to the first, produced by a toroidal current-carrying core magnetically levitated inside the tube.
1960Colgate & Furth in Physics of Fluids III. 999/2 The toroidal analog of the linear hard-core tube is the ‘levitron’, a toroidal pinch tube with a central ring core, levitated by magnetic field or held in place transiently by inertia. 1966McGraw-Hill Encycl. Sci. & Technol. X. 234/2 Several Levitrons are built or under construction. |
