Phase-Space Non-Integrability of Alpha Particles in Near-Omnigeneous Stellarators

A. L. Lachmann, A. R. Knyazev, E. J. Paul

In a burning plasma, fusion-born alpha particles sustain the fusion reaction by heating the plasma core. Alpha-particle confinement in stellarators is sensitive to both deviations…

Nonlinear kinetic closures for linear instabilities

Elizabeth J. Paul, Archis Joglekar, Alexey Knyazev

Landau fluid closures are linear in the evolved moments. We examine the consequences of relaxing linearity. As an example, we introduce the nonlinear exact kinetic response closure…

CATAPULT: A CUDA-Accelerated Timestepper for Alpha Particles Using Local Tricubics

Michael Czekanski, Alexey R. Knyazev, David Bindel +1

We introduce a CUDA-Accelerated Timestepper for Alpha Particles Using Local Tricubics (CATAPULT) for use in Monte Carlo calculations of alpha particle confinement in stellarators.…

On shear Alfvén wave-induced energetic ion transport in optimized stellarators

A. R. Knyazev, A. Lachmann, A. G. Goodman +4

In this work, we investigate prompt ion drift orbit losses caused by shear Alfvén waves (SAW) in quasi-symmetric (QS) and quasi-isodynamic (QI) stellarators optimized for equilibri…

Update on the design of the Columbia Stellarator eXperiment

Antoine Baillod, Avigdor Veksler, Rohan Lopez +4

We present the final configuration chosen to be build for the Columbia Stellarator eXperiment (CSX), a new stellartor experiment at Columbia University. In a recent publication, Ba…
