TFTR

The Tokamak Fusion Test Reactor (TFTR) was a tokamak designed and built at PPPL. It was one of the main fusion research devices in operation from 1982 to 1997. It had a major radius of 2.48 m and a minor radius of 0.85 m, a toroidal magnetic field of 5.6 T and plasma currents around 3 MA.

In December 1993, the team at PPPL started an experimental campaign with the TFTR of 50/50 D-T discharges. During this campaign, TFTR established a world record of 6.3 MW fusion energy production, a milestone previously held by JET. In May 1994, TFTR set another fusion energy production record of 9.2 MW.
