The Advanced Toroidal Facility (ATF) is a new magnetic plasma confinement device, under construction at Oak Ridge National Laboratory (ORNL), which will lead to improvements in toroidal magnetic fusion reactors. ATF is a type of stellarator known as a torsatron, which theoretically has the capability to operate at > or =8% beta in steady state. The achievement of high beta is made possible by the carefully chosen combination of helical and poloidal magnetic field coils which give direct access to the so-called second stability region. In addition, the device has the flexibility to explore the stability boundaries and to study the properties of a variety of magnetic configurations, including some with a helical magnetic axis. The ATF plasma has a major radius of 2.1 m, an average minor radius of 0.3 m, and a field of 2 T for a 5-s duration or 1-T steady state. ATF replaces the ISX-B tokamak at ORNL and will use the ISX-B auxiliary systems, including 4 MW of neutral injection heating and 0.2 MW of electron cyclotron heating. ATF will start operation in the fall of 1986.
