Effect of the tangential NBI current drive on the stability of pressure and energetic particle driven MHD modes in LHD plasma
J. Varela, W. A. Cooper, K. Nagaoka +5
The aim of the present study is to analyze the stability of the pressure gradient driven modes (PM) and Alfven eigenmodes (AE) in the Large Helical Device (LHD) plasma if the rotat…
Analysis of the MHD stability and energetic particles effects on EIC events in LHD plasma using a Landau-closure model
J. Varela, D. A. Spong, L. Garcia +3
The aim of this study is to perform a theoretical analysis of the magnetohydrodynamic (MHD) stability and energetic particle effects on a LHD equilibria, calculated during a discha…
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…
Proto-CIRCUS Tilted-Coil Tokamak-Torsatron Hybrid: Design and Construction
A. W. Clark, M. Doumet, K. C. Hammond +4
We present the field-line modeling, design and construction of a prototype circular-coil tokamak-torsatron hybrid called Proto-CIRCUS. The device has a major radius R = 16 cm and m…
