stellarator

(ˈstɛləˌreɪtə)
n
(General Physics) physics an apparatus used in research into thermonuclear reactions, consisting of a toroidal vessel designed so that a plasma may be contained within it by a helical magnetic field. The magnetic field is produced by current-carrying coils
[C20: from stellar + (gener)ator]

Long-time stellarator advocate and editor of Stel-larator News Jim Rome (ORNL retired) has posted his view of the differences between stellarators and tokamaks at: http://jamesrome.neYdrupal/iter He can be reached at: jamesrome@gmail.com and http://jamesrome.net
Currently two types of fusion devices are being built -- tokamaks and stellarators. India is building its own tokamak at the Institute of Plasma Research in Gandhinagar and is also a key member of an international effort to build a large fusion test device at Cadarche in France.
Test particle runs of the TRAN transport code suggest that for quasineutrality to prevail in tokamaks a certain minimum level of 3D asymmetry of the magnetic spectrum is required which is comparable to that found in quasiaxially symmetric (QAS) stellarators. The computational theory suggests that a QAS stellarator with two field periods and proportions like those of ITER is a good candidate for a fusion reactor.
Topics include ion-acoustic structural turbulence in low-temperature magnetized plasma, low-frequency structural plasma turbulence in stellarators, new possibilities for the mathematical modeling turbulent transport processes in plasma, multi-fractal statistics of edge plasma turbulence, Fractionally stale distribution, and hidden Markov models of plasma turbulence.
The first of the three above-mentioned Agreements was concluded in 1985 with the US Department of Energy (USDOE), concerning the development of the stellarator concept - the term refers generally to all toroidal concepts based on external confinement of fusion plasmas, including stellarators, heliotrons and torsatrons.
could take advantage of working on international facilities on "long-pulse, steady-state research in superconducting advanced tokamaks and stellarators; in steady-state confinement and control science; and in plasma-wall interactions".
He performed pioneering work on stellarators, beginning in 1963, after receiving his diploma in theoretical physics at the University of Munich.
The codes have been used recently to design quasiaxisymmtric stellarators as a possible candidate for a demonstration fusion power plant.
