Stability Analysis of Some Equilibria in a Stabilized Z-Pinch.

摘要

A number of plasma conditions were examined in the linear z-pinch, FUZA-2. Equilibrium radial profiles were measured for the axial and azimuthal magnetic fields and for the density. These equilibria were analyzed with the THALIA and RIPPLE programs to find the wavelength and growth times of the most unstable m=1 modes. These predictions were compared with measurements made of the wave-length and growth times with 120 deg. sector coils under the same plasma conditions. The agreement for the growth times was good for discharge with a low mass density filling, but the experimental values were two times larger than the theoretical ones for the cases with a high mass density filling. In the cases where wavelengths could be measured, the agreement between theory and experiment was good. (Atomindex citation 12:633784)
