托卡马克 device in ITALY; data sourced from IAEA 2022 survey.
FTU is a fusion device or design surveyed by the IAEA in 2022. Operating since 1990, FTU was the first tokamak that performed experiments with a liquid lithium limiter.
Purpose
The main purpose of FTU tokamak is to study and optimize techniques of reduction of the impurities in plasma using different elements, i.e., liquid metal first wall materials [39]. Most of FTU experiments since 2018 are devoted to studies on liquid metal limiters, runaway electrons and MHD stability.
