- An MHD workshop entitled ``Stabilization of the External Kink and Other MHD Issues`` was held June 1993. This is a summary report of activities at that workshop, structured to respond to the three questions in the charge (letter from J. Willis). The experimental and theoretical status of these issues, and the R&D needs in each area, are addressed. We discuss the potential impact on the TPX and ITER programs of these issues. The workshop participants came from a broad and diverse range of institutions in the fusion program, including international participants. As a result, we believe the summary here reflects some consensus of the community on these very important program issues, and that the TPX and ITER programs will benefit from these discussions. The title of the workshop was chosen to indicate both our knowledge and our uncertainty of MHD phenomena limiting β and causing disruptions in tokamaks. The purpose was to bring together theorists and experimentalist in order to assess our current understanding of the external kink instability at high β, and to assess the potential for passive or active stabilization of the dominant modes. We also outlined the R&D needed for TPX and other future devices. Not only was the preworkshop theory clearly presented, but significant new theoretical results were described for the first time, emphasizing the roles of the resistivity of the cold edge plasma and of the plasma toroidicity in the stability criteria. Excellent reviews of the effects of the vessel walls on plasma stability were given as related to the DIII-D, TFTR, JET, PBX-M, and HBT-EP experiments. These results are generally consistent with the more complete theory.
