Abstract

A new MHD model is used to investigate the effect of the pressure anisotropy on the internal kink (m=1) mode instability in a Z-pinch. A normal mode analysis of perturbed motion of an incompressible, collision-less and cylindrical plasma is performed. A comparison of the derived stability criterion with that of ideal MHD is made. The conclusion is that the stability criterion (R-SIGMAB**2)' <= O CANNOT BE FULFILLED WITHOUT VIOLATION OF the fire hose condition SIGMA <= 0, where SIGMA = 1-(P-ii-P-perpendicular)/B**2.
