This report addresses key physics questions of fusion reactor design using the Octopole device. A brief history of Octopole experiments and a description of the work of the past year is given. This work comprised an experiment concerning a divertor-tokamak system and work to prepare a plasma capable of entering the trapped ion mode regime. The first experiment performed concerned the MHD equilibrium and stability of an axisymmetric tokamak-divertor configuration. This work demonstrated that a stable equilibrium is obtainable for a tokamak in which the plasma is bounded by a separate flux surface. Other work concerned the collisionless ion experiment and rf ion heating experiment. Work was also done on the plasma source and in obtaining proper diagnostics (devices to measure plasma density, neutral density, and ion and electron temperatures) for this new plasma. A plasma that can enter the trapped ion mode regime with the addition of rf heating has been obtained, and the means for diagnosing the plasma have been developed. (GRA)
