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 equilibr…

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…

The shear Alfvén continuum of quasisymmetric stellarators
Elizabeth J. Paul, Abdullah Hyder, Eduardo RodrÃguez +2
The shear Alfvén wave (SAW) continuum plays a critical role in the stability of energetic particle-driven Alfvén eigenmodes. We develop a theoretical framework to analyze the SAW…
