Abstract
The stability of the pinch for an equilibrium case which has sheet currents at the surface of the pinch and a uniform pressure inside the plasma has been investigated. In addition, there was an axial magnetic field in the plasma interior, a different axial field in the outer region, and a conducting wall. The pinch stability by the method of normal modes for an equilibriuun case in which the plasma contains a uniform volume current in the axial direction and a pressure which varies parabolically in the radial direction has also been investigated. However, although axial magnetic fields were considered in this case they were taken to be equal in the interior and exterior and no external conductmg wall was used. Here this analysis is extended to include a finite axial field in the plasma interior with no external axial field. In addition, there is now an external conducting wall. The resulting dispersion relation is discussed. (auth)
