Theoretical analysis of energetic-ion-driven resistive interchange mode stabilization strategies using a Landau closure model
J. Varela, S. Ohdachi, K. Y. Watanabe +3
The aim of the present study is to perform a theoretical analysis of different strategies to stabilize energetic-ion-driven resistive interchange mode (EIC) in LHD plasma. We use a…
Modeling of the ECCD injection effect on the Heliotron J and LHD plasma stability
J. Varela, K. Nagasaki, K. Nagaoka +6
The aim of the study is to analyze the stability of the Energetic Particle Modes (EPM) and Alfven Eigenmodes (AE) in Helitron J and LHD plasma if the electron cyclotron current dri…
Spatially-dependent modeling and simulation of runaway electron mitigation in DIII-D
M. T. Beidler, D. del-Castillo-Negrete, L. R. Baylor +2
New simulations with the Kinetic Orbit Runaway electron (RE) Code KORC show RE deconfinement losses to the wall during plasma scrape off are the primary current dissipation mechani…
Subdominant modes and optimization trends of DIII-D reverse magnetic shear configurations
J. Varela, D. A. Spong, M. Murakami +4
Alfven Eigenmodes and magneto-hydrodynamic modes are destabilized in DIII-D reverse magnetic shear configurations and may limit the performance of the device. We use the reduced MH…
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…
