This book bridges the gap between general plasma physics lectures and the real world problems in MHD stability. In order to support the. A new formalism for analyzing the magnetohydrodynamic stability of a limiter tokamak edge plasma is developed. Two radially localized, high toroidal mode.

Variational theory is used to derive a generalized Euler equation and a new energy functional which are convenient for analytical studies of ideal. The ideal magnetohydrodynamic MHD stability of the tokamak edge is analyzed, 1 tokamak equilibria indicate that two types of instability are important: the. The results of extensive investigations of the low-n ideal magnetohydrodynamic stability of the TCV, NET and DIII-D tokamaks are compared in order to identify.

11 May Special Issue on the 20th Workshop on MHD Stability Control . as three- dimensional magnetohydrodynamic tokamak equilibrium states Phys. Ideal-MHD stability of the ISX-B tokamak. L.A. Charlton1, D.K. Lee1, R.M. Wieland1, B.A. Carreras2, W.A. Cooper2 and G.H. Neilson2. Nuclear Fusion, Volume. necessary for achieving MHD stable reactor grade conditions. Appropriate tokamak MHD equilibria will be described, Then the stability properties is discussed. Achieving very high _3and high/3p simultaneously in tokamaks generally im- j, plies that libria which are stable to all ideal MHD modes, in particular, the n -- 1 . A new formula, describing the ideal MHD stability dependence on plasma toroidicity and shape parameters is proposed for use in modern tokamaks and future.

10 Jan In tokamaks, it is well known that instabilities are primarily driven by The impact of energetic ions on MHD stability is exemplified in a recent. Recent theoretical and experimental research has made important advances in both understanding and control of MHD stability in tokamak plasmas. Sawteeth. However, MHD stable plasmas do not necessarily mean that they are free from finer scale and stability will be outlined for tokamak magnetic configurations. A new linear MHD stability code MINERVA is developed for investigating a toroidal rotation effect on the stability of ideal MHD modes in tokamak plasmas.
