Definition of stellarator in English:
stellarator
noun ˈstɛləreɪtəˈsteləˌrādər
Physics A toroidal apparatus for producing controlled fusion reactions in hot plasma, where all the controlling magnetic fields inside it are produced by external windings.
Example sentencesExamples
- Research is being carried out on several types of stellarator differing mainly in the periodicity of the toroidal and poloidal components of their magnetic field.
- The design techniques and physics analysis of modern stellarator configurations for magnetic fusion research rely heavily on high performance computing and simulation.
- New stellarators beat the confinement problem by creating a quasi-symmetric field - trading fiendishly complex magnetic fields for fiendishly complex magnets.
- A stellarator is machine that is designed for the magnetic confinement of plasma.
- These low-aspect-ratio stellarator-tokamak hybrids differ from conventional stellarators in their use of the plasma-generated bootstrap current to supplement the poloidal field from external coils.
Origin
1950s: from stellar (with reference to the fusion processes in stars), on the pattern of generator.
