Quasi-isodynamic stellarators with low turbulence as fusion reactor candidates
Alan G. Goodman, Pavlos Xanthopoulos, Gabriel G. Plunk +7
The stellarator is a type of fusion energy device that - if properly designed - could provide clean, safe, and abundant energy to the grid. To generate this energy, a stellarator m…
A single-field-period quasi-isodynamic stellarator
R. Jorge, G. G. Plunk, M. Drevlak +4
A single-field-period quasi-isodynamic stellarator configuration is presented. This configuration, which resembles a twisted strip, is obtained by the method of direct construction…
Optimization of quasisymmetric stellarators with self-consistent bootstrap current and energetic particle confinement
Matt Landreman, Stefan Buller, Michael Drevlak
Quasisymmetry can greatly improve the confinement of energetic particles and thermal plasma in a stellarator. The magnetic field of a quasisymmetric stellarator at high plasma pres…
Energetic particle transport in optimized stellarators
A Bader, D T Anderson, M Drevlak +7
Nine stellarator configurations, three quasiaxisymmetric, three quasihelically symmetric and three non-quasisymmetric are scaled to ARIES-CS size and analyzed for energetic particl…
Representing the boundary of stellarator plasmas
Sophia A. Henneberg, Per Helander, Michael Drevlak
In stellarator optimization studies, the boundary of the plasma is usually described by Fourier series that are not unique: several sets of Fourier coefficients describe approximat…
A New Optimized Quasihelically SymmetricStellarator
A. Bader, B. J. Faber, J. C. Schmitt +12
A new optimized quasihelically symmetric configuration is described that has the desir-able properties of improved energetic particle confinement, reduced turbulent transportby 3D…
Stellarators with permanent magnets
P. Helander, M. Drevlak, M. Zarnstorff +1
It is shown that the magnetic-field coils of a stellarator can, at least in principle, be substantially simplified by the use of permanent magnets. Such magnets cannot create toroi…
Properties of a new quasi-axisymmetric configuration
S. A. Henneberg, M. Drevlak, C. Nührenberg +4
A novel, compact, quasi-axisymmetric configuration is presented which exhibits low fast-particle losses and is stable to ideal MHD instabilities. The design has fast-particle loss…
Energetic electron transport in the presence of magnetic perturbations in magnetically confined plasmas
Gergely Papp, Michael Drevlak, Gergő I. Pokol +1
The transport of energetic electrons is sensitive to magnetic perturbations. By using 3D numerical simulation of test particle drift orbits we show that the transport of untrapped…
