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 کاملInvestigations of Magnetohydrodynamic Instabilities in the STOR-M Tokamak
Studies of magnetohydrodynamic (MHD) instabilities in the Saskatchewan Torus-Modified (STOR-M) tokamak have been conducted to examine the mode structures and time evolution during the Ohmic discharges and after compact torus (CT) injection. External discrete Mirnov coils and two pin-hole soft x-ray (SXR) cameras have been used for the studies. The time-resolved frequency component analysis has ...
متن کاملControl of magnetohydrodynamic stability by phase space engineering of energetic ions in tokamak plasmas.
Virtually collisionless magnetic mirror-trapped energetic ion populations often partially stabilize internally driven magnetohydrodynamic disturbances in the magnetosphere and in toroidal laboratory plasma devices such as the tokamak. This results in less frequent but dangerously enlarged plasma reorganization. Unique to the toroidal magnetic configuration are confined 'circulating' energetic p...
متن کاملIdeal Magnetohydrodynamic Stability Limits of a High Tokamak with Superimposed Helical Fields
The stability of a high 3 tokamak with a superimposed single helicity stellarator field is investigated in the context of the sharp boundary surface current model. The analysis treats external ideal magnetohydrodynamic modes including both pressure-driven ballooning effects and current-driven kink instabilities. The results show that the addition of an i = 2 field is unfavorable, lowering the a...
