Behavior of kinetic instabilities in a dynamically forming resonant distribution
E. J. Hartigan-O'Connor, T. Barberis, E. G. Devin +2
Instabilities driven by energetic particles are central to the physics of a burning plasma. The majority of kinetic simulations and reduced models assume that the unstable distribu…

Perturbative model for the saturation of energetic-particle-driven modes limited by self-generated zonal modes
Tommaso Barberis, VinÃcius N. Duarte, Eamon J. Hartigan-O'Connor +1
We present a simplified approach enforcing energy conservation to incorporate the effects of zonal modes alongside wave-particle nonlinearities in the determination of the saturati…
