Description
ST25-HTS is a follow on device to ST25. It uses REBCO high-temperature superconductor coils in both the toroidal and poloidal field coils. ST25-HTS is the first tokamak to use these superconductors for both sets of coils. In 2015, ST25-HTS ran its magnets and sustained a plasma continuously for 29 hours.
