Finite beta toroidal plasmas

These four papers on high-..beta.. tokamak instabilities, fundamental time scales for flux conserving tokamak heating, intense tokamak heating in the adiabatic approximation, and the Elmo Bumpy Torus were presented at the Workshop on High Beta Tokamaks held at Varenna, Italy on September 1--9, 1977. They will be included in the proceedings of that meeting, to be published by the Department of Energy.
