Quasi-single-stage optimization for permanent magnet stellarators
Nuclear FusionAdvanced stellarators are typically optimized in two stages. The plasma equilibrium is optimized first, followed by the design of coils/permanent magnets.

Nuclear FusionStellarators mainly utilize magnetic fields from external coils to confine the plasma, enabling steady-state operation while avoiding instabilities like disruptions raised from plasma currents.

, 2002 Stellarators are toroidal devices where the required rotational transform of the magnetic field lines is generated by external field coils and not via an induced net toroidal plasma current.

Simplified and Flexible Coils for Stellarators using Single-Stage Optimization
Single-stage optimization, also known as combined plasma-coil algorithms or direct coil optimization, has recently emerged as a possible method to expedite the design of stellarator devices by including, in a single step, confinement, stability, and ...

Optimizing stellarators for large flows
, 2014 Plasma flow is damped in stellarators because they are not intrinsically ambipolar, unlike tokamaks, in which the flux-surface averaged radial electric current vanishes for any value of the radial electric field.

Neoclassical transport in quasi-axially symmetric stellarators [PDF]
, 1997 The author presents a numerical and analytic assessment of the transport in two quasi-axially symmetric stellarators, including one variant of the MHH2 class of such devices, and a configuration they refer to as NHH2, closely related to MHH2. Monte Carlo

On a stellar structure for a stellar manifold
, 2002 It is well known that a compact two dimensional surface is homeomorphic to a polygon with the edges identified in pairs. This paper not only presents a new proof of this statement but also generalizes it for any connected n-dimensional stellar manifold with a finite number of vertices.

Hydromagnetic stability of a plasma in stellarators
, 1969 It is shown that, with the help of the sufficient criterion for hydromagnetic stability of a plasma proposed by Solovev, It is possible to calculate for stellarators a non-trivial plasma pressure limit at which there is hydromagnetic plasma stability ...
