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…
