“…One of the key problems encountered in order to get the solution of the above set of integrodifferential equations has been the weak convergence (in the right neighbourhood of the time origin) of the series expansions which represent the functions H and K (NALESSO, 1982). One must remember that the whole problem is solved as an initial value problem, so that the knowledge of every function near the time origin is essential for finding the solution.…”

“…This case, however, cannot be derived simply by letting the conductivity of the wall go to zero in the previous case. The reason is in the fact that for a non-zero conductivity, it is necessary to assume a discontinuity in the normal component of the electric field at the boundary between the conducting material and the vacuum region to assure the vznishing oT the normal component of the current density at the same surface (NALESSO, 1982). This discontinuity is no longer realistic when the whole region (insulating vessel and vacuum) is non-conducting.…”

“…For an ideal MHD plasma, this problem has been already solved [see e.g. (GOEDBLOED, 1972;NALESSO, 1980)], while for the full non-ideal MHD stability (i.e. the stability of a resistive fluid with viscosity and other dissipative effects added) only recently (NALESSO, 1984) the problem has been tackled.…”

The stability against resistive tearing and interchange modes for an inviscid incompressible plasma confined by a resistive rigid wall is studied. The limiting case of a non conducting rigid wall is also examined in some detail. Results for equilibrium configurations of the reversed field pinch type are presented for both cases. In particular the high beta pitch and pressure model and experinental profiles for the Eta Beta I1 R F P are considered and the results are compared with the classical (i.e. infinite conducting wall) case.

A new set of boundary conditions for a resistive plasma that takes into account the effect of a nonideal rigid wall of finite conductivity and thickness, is derived. These conditions, in cylindrical geometry, take the form of a system of integrodifferential equations involving the perturbed plasma variables v1, B1, T1, at the inner surface of the rigid wall. This system of integrodifferential equations is numerically solved, using a numerically stable scheme, and is implemented in an existing linear one-dimensional resistive initial value code, the Ripple IVA, developed by Dibiase and Killeen [Comput. Phys. 24, 158 (1977)]. An approximate solution of the problem, valid in a neighborhood of the time origin, is also derived. Attention is then focused on the linear behavior of resistive tearing and interchange modes as a function of the ratio of plasma and wall conductivity as well as the magnetic Lundquist number S, especially for high-beta equilibria of the reversed field pinch (RFP) type.
