Spectrum of ballooning instabilities in a stellarator

The recent revival of interest in the application of the ''ballooning formaiism'' to low-frequency plasma instabilities has prompted a comparison of the Wentzel-Kramers-Brillouin (WKB) ballooning approximation with an (in principle) exact normal mode calcu ...

Effect of Quadrupole Fields on Local 3-Dimensional (3-D) Ideal Magnetohydrodynamic (Mhd) Stability in Torsatrons

Wilfred Anthony Cooper

The local three-dimensional (3-D) ideal magnetohydrodynamic (MHD) stability properties of a 12-field period torsatron device of moderate aspect ratio are investigated as a function of an externally applied quadrupole magnetic field. It is demonstrated that ...

Coaxial Plasma Gun in the High-Density Regime and Injection into a Helical Field

A modified CPG in the high density regime of 20-70mT of He was investigated. The injection of the plasmatorus into a driftspace was studied by diamagnetical diagnostics both with and without helical bias, where the inner electrode was continued into the dr ...

On a 2-Dimensional Magnetohydrodynamic Problem .1. Modeling and Analysis

Jacques Rappaz

We consider a two-dimensional Magnetohydrodynamic system of equations describing the motion of a conducting fluid in which eddy currents flow. The mathematical model is derived and existence of solutions is proved by using fixed point techniques. Uniquenes ...
