ABSTRACT
A historical survey is given of the experimental multipole and tokamak
fusion research programme carried out at the University of Wisconsin since
1962. The programme has concentrated on axisymmetric toroidal confinement
through the utilization of a series of different multipole devices and
of a poloidal divertor tokamak. The gross plasma stability and good confinement
properties of the multipoles led to a number of experimental results not
easily achievable in other toroidal devices. The paper describes the major
results obtained in multipoles with and without Ohmic heating current and
toroidal field, and their influence on the development of plasma theory.
In the poloidal divertor tokamak, stable discharges have been found at
very low values of the safety factor.
