Technical Overview and Electrical Design of the Tokamak de Varennes

Abstract

The Tokamak de Varennes, Canada's contribution to tokamak-oriented fusion research, is beginning experimental operation in the spring of 1987. The scientific vocation of this medium-sized tokamak experiment is the investigation of plasma-wall interaction and surface studies in a long-pulse mode. This program has been the dtetermining factor in the design of the Tokamak de Varennes, leading, for instance, to demountable toroidal field coils, to an elaborate power supply for the olmic heating system, to complex internal structures, to a powerful


cooling system. This paper gives a general description of the experimental device, and discusses its power supplies in a more detailed fashion.
