Spacecraft heat shield study in the DIII-D tokamak
Dmitri M. Orlov, Evdokiya G. Kostadinova, Igor Bykov +33
We report a new experimental platform developed at the DIII-D National Fusion Facility to investigate carbon ablation and spallation under extreme heat fluxes relevant to fusion pl…
Effect of the neutral beam injector operational regime on the Alfven eigenmode saturation phase in DIII-D plasma
J Varela, D A Spong, L Garcia +11
The aim of this study is to analyze the effect of the neutral beam injector (NBI) operation regime on the saturation phase of the Alfven Eigenmodes (AEs) in DIII-D plasma. The anal…
Design and simulation of an Imaging Neutral Particle Analyzer for the ASDEX Upgrade tokamak
J. Rueda-Rueda, M. Garcia-Munoz, E. Viezzer +10
An Imaging Neutral Particle Analyser (INPA) diagnostic has been designed for the ASDEX Upgrade (AUG) tokamak. The AUG INPA diagnostic will measure fast neutrals escaping the plasma…
Onset of nonlinear structures due to eigenmode destabilization in tokamak plasmas
Vinicius Duarte, Herbert Berk, Nikolai Gorelenkov +5
A general methodology is proposed to differentiate the likelihood of energetic-particle-driven instabilities to produce frequency chirping or fixed-frequency oscillations. The meth…
Prediction of Nonlinear Evolution Character of Energetic-Particle-Driven Instabilities
Vinicius Duarte, Herbert Berk, Nikolai Gorelenkov +7
A general criterion is proposed and found to successfully predict the emergence of chirping oscillations of unstable Alfvénic eigenmodes in tokamak plasma experiments. The model in…
Energetic particle instabilities in fusion plasmas
S E Sharapov, B Alper, H L Berk +41
Remarkable progress has been made in diagnosing energetic particle instabilities on present-day machines and in establishing a theoretical framework for describing them. This overv…
