The compact fusion energy experimental device project campus has been delivered for use.

On October 1, it was learned in Hefei Future Science City, Anhui, that the national major engineering project herethe Compact Fusion Energy Experimental Device project parkwas delivered for use ahead of schedule, and the construction of the device's main machine has entered the "four-ring assembly" critical stage. Since July this year, key core components of the BEST device, including the vacuum vessel, cold screen, and toroidal field magnets, have been successively transported to the site. At present, the four vacuum main machine modules have been smoothly positioned and installed, all tests on the first set of toroidal field magnets have been completed, and the device's main machine has officially started the "four-ring assembly" critical phase, that is, the sequential assembly from the inside outward of core components such as the vacuum vessel, cold screen, toroidal field magnets, and internal components. The BEST device is China's independently developed next-generation fusion energy burning experimental device. Its goal is to take the lead in carrying out scientific and technological research on deuterium-tritium fusion energy burning under long-duration reactor conditions, explore the scientific and engineering feasibility of tokamak fusion reactors, and lay the key technical and engineering foundation for the future commercial application of fusion energy engineering.
