NORMAL-MODE TREATMENT OF PINCH INSTABILITIES
The pbenomenon of tbe pinch effect and the moat common modes of instability to which it is susceptible are discussed. It was found by mathematical analysis that if the pinch was perturbed radially, the system would be subject to sausage instabilities, and if perturbed laterally, it could experience kink instability. In the absence of an internal axial magnetic field and exterior conducting surface, the pinch was found to be unstable for all real values of the perturbation wave number. By including an axial magnetic field within the plasma, the system was stabilized against the sausage instabllity for very small and very large values of ths perturbation wave number. With an externally conducting plasma surface, the kink instability is stabilized for small perturbation wave numbers. (M.C.G.)
