PLT

The Princeton Large Torus (PLT) was a tokamak built in PPPL in 1975. It had a major radius of 1.32 m and a minor radius of 0.40 m, which made it one of the largest devices of its time. PLT was initially used in Ohmic and neutral beam heating research but was later used in RF heating research too. During its lifetime, PLT achieved some important results like setting record ion temperatures using either neutral beam injection or RF heating methods. In December 1986, PLT ceased operations.
