Optimization of energy confinement in the 1/ν regime for stellarators

Journal of Computational Physics, 2008
For certain conditions the stellarator magnetic field can be originally obtained in the real space coordinates and there is no necessity in its transformation to magnetic coordinates. A procedure working in real space coordinates is presented for maximizing the plasma energy content, based on reducing the most unfavorable \(1/\nu\) neoclassical ...

Stellaris: A high-field quasi-isodynamic stellarator for a prototypical fusion power plant

Fusion Engineering and Design
Magnetic confinement fusion research has so far prioritized the tokamak concept, which presents greater design simplicity at the cost of control complexity in comparison to stellarators.

A proof-of-concept for automated AI-driven stellarator coil optimization with in-the-loop finite-element calculations

arXiv.org
Finding feasible coils for stellarator fusion devices is a critical challenge of realizing this concept for future power plants. Years of research work can be put into the design of even a single reactor-scale stellarator design.

The theoretical basis of a drift-optimized stellarator reactor

Plasma Physics and Controlled Fusion, 1993
The stellarator is a 3-dimensional toroidal configuration without induced toroidal plasma currents. The magnetic field is produced by external coils which allows steady-state operation of a stellarator reactor. The requirements coming from reactor conditions narrow the range of potential stellarator configurations as reactor candidates; therefore an ...

Turbulent and Collisional Transport in Optimized Stellarators

2020
The stellarator is a fusion energy concept that relies on fully three-dimensional shaping of magnetic fields to confine particles. Stellarators have many favorable properties, including, but not limited to, the ability to operate in steady-state, many optimizable degrees of freedom, and no strict upper limit on the plasma density.

Some results of stellarator optimization

2015
The collisionless confinement of all reflected particles with orbits that star within the inner half of the plasma of a stellarator with the poloidal direction of the contours of the magnetic field strenght B is shown computationally to be possible. It is also demonstrated that the confinement achieved is well compatible with the fulfilment of Mercier ...
