Experimental axisymmetric toroidal confinement research has been pursued at the University of Wisconsin through the utilization of multipole and tokamak devices. Multipoles facilitated the controlled study of key confinement issues since in a single device one is able to vary, over a wide range, critical plasma parameters including ohmic current level, collisionality, field transform, magnetic shear and plasma beta. This feature, and the natural quiescence of multipole plasmas, has been exploited for over twenty years at Wisconsin through a sequence of different multipole devices culminating in the Levitated Toroidal Octupole. Important aspects of toroidal plasma equilibrium, stability, heating and transport have been studied which often could not be addressed in existing tokamaks. Toroidal confinement research using the Tokapole II poloidal divertor tokamak began in 1977, with emphasis on issues relating to the magnetic limiter topology.
