We present a novel method for numerically finding quasi-isodynamic stellarator magnetic
fields with excellent fast-particle confinement and extremely small neoclassical transport …

A new quasi-isodynamic (QI) stellarator configuration optimized for the confinement of
energetic ions at low plasma β is obtained. The numerical optimization is carried out using …

Collisionless physics primarily determines the transport of fusion-born alpha particles in 3D
equilibria. Several transport mechanisms have been implicated in stellarator configurations …

Stellarator magnetic configurations need to be optimized in order to meet all the required
properties of a fusion reactor. In this work, it is shown that a flat-mirror quasi-isodynamic (QI) …

In omnigenous magnetic fields, charged particles are perfectly confined in the absence of
collisions and turbulence. For this reason, the magnetic configuration is optimized to be …

This paper presents the calculation of the bounce-averaged drift of trapped particles in a
near-axis framework for axisymmetric and quasisymmetric magnetic fields that possess up …

This report presents an initial analysis of the fast ion confinement and losses within quasi-
axisymmetric stellarator equilibria in consideration by Thea Energy. The equilibria have not …

A new perturbation and continuation method is presented for computing and analysing
stellarator equilibria. The method is formally derived from a series expansion about the …

In tokamaks and neoclassically optimised stellarators, like Wendelstein 7-X (W7-X) and the
Helically Symmetric Experiment, turbulent transport is expected to be the dominant transport …
