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: email@example.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.
