ACT-1

The Advanced Concept Torus (ACT-1) was a steady state toroidal device which was operated at PPPL. Its vacuum chamber was made of aluminum with a water cooling system and 26 toroidal field coils capable of produce a 0.56 T magnetic field on the axis. ACT-1 had a toroidal plasma with a minor radius of 10 cm and a major radius of 59 cm. It was used for the study of radiofrequency heating, specifically in lower hybrid waves and ion cyclotron waves. In 1985, ACT-1 was converted into the Current Drive Experiment (CDX)
