Microturbulence-mediated route for energetic ion transport and Alfvénic mode intermittency in tokamaks
Nikolai Gorelenkov, Vinicius Duarte
We report on a theoretical discovery of new regimes of Alfvén eigenmode (AE) induced fast ion transport in tokamak plasmas, where microturbulence plays the role of a mediator of fa…

Study of the likelihood of Alfvénic mode bifurcation in NSTX and predictions for ITER baseline scenarios
Vinicius Duarte, Nikolai Gorelenkov, Mirjam Schneller +3
Rare Alfvénic wave transitions between fixed-frequency and chirping phases are identified in NSTX, where Alfvénic waves are normally observed to exhibit either chirping or avalanch…
