FIG. 1.

The growth rate of the unstable free boundary kink mode depends on the location and time constant of the resistive wall. The plasma has a constant axial current density with , , , , , , and the discretization grid has 20 points.

The product of the wall time and the growth rate of the RWM (i.e., ) as a function of showing that for large enough wall times. The plasma parameters are the same as those of Fig. 1. The number labels indicate the wall location for that curve.

Ideal MHD spectrum in the complex plane for various values of with the plasma parameters of Fig. 1 and . The letter-labeled modes are as follows: F, fast; A, Alfvén; S, sound.
