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 ...

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

FOCUS-HTS: a new stellarator coil design code for three-dimensional high-temperature superconducting magnets

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

Density profiles in stellarators: an overview of particle transport, fuelling and profile shaping studies at TJ-II

Nuclear Fusion
We provide an overview of activities carried out at the TJ-II stellarator for improving our understanding of- and developing plasma physics models for particle density profiles in stellarators.

Assessment of stellarators as reactors

, 1993
Stellarators have significant operational advantages over tokamaks as ignited steady-state reactors: no dangerous disruptions, no need for continuous current drive and power recirculated to the plasma, less severe constraints on the plasma parameters and

Energy confinement comparison of ohmically heated stellarators to tokamaks [PDF]

, 1979
An empirical scaling prescribes that the energy confinement time in ohmically heated stellarators and tokamaks is proportional to the internal energy of the plasma and the minor radius, and inversely proportional to the current density.

Nonlinear saturation of ballooning modes in stellarators

Nuclear Fusion
Ballooning mode saturation is investigated in realistic stellarator configurations using the flux tube approach of Ham et al (2018 Plasma Phys. Control. Fusion 60 075017), Ham et al (2016 Phys. Rev. Lett. 116 235001). The method is adapted to account for
