FIRM3D: Fast ion reduced models in 3D

Elizabeth Paul, Alexey Knyazev, Michael Czekanski +4

The dynamics of energetic particle (EP) species, born from fusion reactions or plasma heating schemes, are critical for predicting the behavior of magnetic confinement fusion exper…

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…

The shear Alfvén continuum of quasisymmetric stellarators

Elizabeth J. Paul, Abdullah Hyder, Eduardo Rodríguez +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…

Ray-tracing laser-deposition model for plasma particle-in-cell simulation

Abdullah Hyder, Will Fox, Kirill Lezhnin +1

We develop a ray-tracing model for laser-plasma interaction suitable for coupling in-line into kinetic particle-in-cell plasma simulation. The model is based on inverse Bremsstrahl…
