Magnetohydrodynamic stability analyses of tokamak edge plasmas
s of publications 1-5: 1. An ELMy ASDEX Upgrade plasma equilibrium is reconstructed taking into accountthe bootstrap current. The peeling mode stability of the equilibrium is numericallyanalysed using the GATO [1] code, and it is found that the bootstrap current candrive the plasma peeling mode unstable. A high-n ballooning mode stability analysisof the equilibria revealed that,...
متن کاملGyrokinetic simulation model for kinetic magnetohydrodynamic processes in magnetized plasmas
A nonlinear gyrokinetic simulation model incorporating equilibrium current has been formulated for studying kinetic magnetohydrodynamic processes in magnetized plasmas. This complete formulation enables gyrokinetic simulation of both pressure-gradient-driven and current-driven instabilities as well as their nonlinear interactions in multiscale simulations. The gyrokinetic simulation model recov...
متن کاملIndirect Visibility of Gravitational Waves in Magnetohydrodynamic Plasmas
We propose a mechanism to make gravitational waves (GWs) visible in the electromagnetic domain. Gravitational waves that propagate through a strongly magnetized plasma interact with the plasma through its anisotropic stress-energy tensor and excite magnetohydrodynamic (MHD) wave modes. In catastrophic events such as the merger of a double neutron star binary, a large fraction of the total bindi...
متن کاملTheory for explosive ideal magnetohydrodynamic instabilities in plasmas.
Flux tubes confined in tokamaks are observed to erupt explosively in some plasma disruptions and edge localized modes. Similar eruptions occur in astrophysical plasmas, for example, in solar flares and magnetospheric substorms. A single unifying nonlinear evolution equation describing such behavior in both astrophysical and tokamak plasmas is derived. This theory predicts that flux tubes rise e...
متن کاملGeneralized Relativistic Magnetohydrodynamic Equations for Pair and Electron-Ion Plasmas
We derived one-fluid equations based on a relativistic two-fluid approximation of e pair plasma and electron-ion plasma to reveal the specific relativistic nature of their behavior. Assuming simple condition on the relativistic one-fluid equations, we propose generalized relativistic magnetohydrodynamic (RMHD) equations which satisfy causality. We show the linear analyses of these equations reg...
