The construction of the Compact Fusion Experimental Device (BEST) in China has reached a new milestone as the project campus was officially delivered and put into operation. This facility is designed to simulate nuclear fusion reactions occurring within the Sun to generate clean energy.
Assembly of the device is currently underway, with over half of the tasks completed since July. The project has now entered the critical phase known as the four-ring assembly, which involves installing the vacuum chamber, cold screen, and toroidal field magnets.
The toroidal field magnets are engineered to generate a powerful magnetic field, preventing high-temperature plasma from contacting the container walls. This technical configuration is essential for maintaining the stability of the fusion process within the experimental reactor.
According to the project schedule, the overall construction of the BEST facility is expected to be finalized by the end of 2027. Following this, researchers aim to conduct deuterium-tritium fusion power generation demonstrations around 2030 to test commercial viability.
