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…
Slow modes in the Hermean magnetosphere: effect of the solar wind hydrodynamic parameters and IMF orientation
J. Varela, F. Pantellini, M. Moncuquet
The aim of this study is to simulate the slow mode structures in the Hermean magnetosphere. We use a single fluid MHD model and a multipolar expansion of the Northward displaced He…
Plasma streams in the Hermean dayside magnetosphere: solar wind injection through the reconnection region
J. Varela, F. Pantellini, M. Moncuquet
The aim of this research is to simulate the interaction of the solar wind with the magnetic field of Mercury and to study the particle fluxes between the magnetosheath and the plan…
The effect of interplanetary magnetic field orientation on the solar wind flux impacting Mercury's surface
J. Varela, F. Pantellini, M. Moncuquet
The aim of this paper is to study the plasma flows on the Mercury surface for different interplanetary magnetic field orientations on the day side of the planet. We use a single fl…
