[f. stellar a. (see quot. 1951) + L. -ātor (see -or 2 and cf. Eng. generator).]
One kind of toroidal apparatus for producing controlled fusion reactions in a hot plasma, distinguished by the fact that all the controlling magnetic fields inside it are produced by external windings.
1951L. Spitzer Proposed Stellarator (U.S. Atomic Energy Commission NYO-993) 4 Since the proposed system generates power and neutrons by reactions similar to those occurring in the stars, the device analyzed below is called a ‘Stellarator’. 1967Condon & Odishaw Handbk. Physics (ed. 2) iv. xi. 209/2 The feature that distinguishes a stellarator from a torus with solenoidal windings alone is the presence of helical windings around the channel which cause the magnetic-field lines to be twisted in such a way that as the particles drift they are constantly turned back toward the channel center. 1980Ann. Rep. U.K. Atomic Energy Authority 1979–80 32/1 Another type of toroidal magnetic trap studied at Culham is the stellarator. 1981Nature 19 Feb. 625/1 The tokamak must create the longitudinal current in the plasma by a transformer effect, and so must be pulsed. The stellarator, on the other hand, can in principle be run statically. |
