On October 1, I learned at the Future Science City in Hefei, Anhui, that the compact fusion energy experimental device project park, a major national project here, was put into use ahead of schedule, and the construction of the main unit has entered the “four-ring package” attack stage. Since July of this year, the BEST device's key core components such as vacuum chambers, cold screens, and circumferential field magnets have arrived at the site one after another. At present, the four-stage vacuum host components have been successfully installed, all tests of the first set of circumferential field magnets have been completed, and the main unit has officially launched the “four-ring package” campaign, that is, core components such as the vacuum chamber, cold screen, annular field magnets, and internal components work in sequence from the inside out. The BEST device is a next-generation fusion energy combustion experimental device independently developed by China. The goal is to pioneer scientific and technological research on fusion energy deuterium-tritium combustion under long-term reactor conditions, explore the scientific and engineering feasibility of tokamak fusion reactors, and lay the key technical and engineering foundation for future commercialization of fusion energy engineering.
