Tokamak de Varennes: The Design of Its Internal Poloidal Field Cells

Abstract

One of the major projects in Canada's fusion programme i s the Tokamak de Varennes, a medium-sized tokamak now under construction at the Institut de Recherche de l'Hydro-Qugbec (IREQ) at Varennes, Quebec. In order to control impurities within its plasma, the Tokamak will be equipped with two sets of divertor coils and neutralizing plates. The main divertor coils are designed for a total current of 50 kiloampere turns and are located inside 73 mm diameter jackets; this paper describes the design of these coils.
