Analysis of Alfven Eigenmodes destabilization by energetic particles in TJ-II using a Landau-closure model
J. Varela, D. Spong, L. Garcia
Alfven Eigenmodes (AE) can be destabilized by energetic particles in neutral beam injection (NBI) heated plasmas through inverse Landau damping and couplings with gap modes in the…
Analysis of Alfven Eigenmodes destabilization by energetic particles in Large Helical Device using a Landau-closure model
J. Varela, D. A. Spong, L. Garcia
Energetic particle populations in nuclear fusion experiments can destabilize Alfv\' en Eigenmodes through inverse Landau damping and couplings with gap modes in the shear Alfv\' en…
The internal disruption as hard MHD limit of 1/2 sawtooth like activity in Large Helical Device
J. Varela, K. Y. Watanabe, S. Ohdachi
LHD inward-shifted configurations are unstable to resistive MHD pressure-gradient-driven modes. Sawtooth like activity was observed during LHD operation. The main drivers are the u…
Internal disruptions and sawtooth like activity in LHD
J. Varela, L. Garcia, S. Ohdachi +2
LHD inward-shifted configurations are unstable to resistive MHD pressure-gradient-driven modes. These modes drive sawtooth like events during LHD operation. In this work, we simula…
