The Frascati Tokamak Upgrade (FTU) is a tokamak operating at Frascati, Italy, under the ENEA fusion research program. Building on the Frascati Tokamak experiment, FTU is a compact, high-magnetic-field tokamak. The magnetic field on the axis of FTU's torus, created by its toroidal field coils, is 8 tesla. This is substantially higher than most magnetic confinement fusion devices, including the largest tokamaks ever built such as JET and TFTR, which have magnetic field strengths in the range of 3-5.5 T.
FTU began operation in 1990 and has since achieved operating goals of 1.6 MA at 8 T and average electron density greater than 4×1020 per cubic meter. The poloidal section of FTU is circular, with a limiter.
A similar small high-field tokamak in the USA was Alcator C-Mod at the Massachusetts Institute of Technology. Both experiments were cited as a basis for the IGNITOR tokamak proposal. Italian MIT professor Bruno Coppi worked on all three programs.[2]
