2025年度合肥聚变十大创新成果

Group 1 - The "artificial sun" has achieved a world record by maintaining a steady-state long pulse plasma operation at over one billion degrees Celsius for 1066 seconds [1] - The BEST project has successfully initiated the assembly of its main components, with the Dewar base positioned with millimeter-level precision [2] - The first PF magnet for the BEST project has been completed, measuring over 10 meters in diameter, 2.5 meters in height, and weighing over 100 tons, taking 30 months to manufacture [3] Group 2 - The BEST research plan has been officially released globally, with over ten countries' scientists signing the "Hefei Fusion Declaration" [4] - The domestically developed high-strength steel No. 1 has filled a gap in the application of high-strength, tough, non-magnetic structural materials under extreme low-temperature conditions [5] - An international superconducting linear plasma device has been constructed, featuring a maximum particle flow greater than 10^24 m^-2 s^-1 and a discharge time exceeding 1000 seconds [6] Group 3 - The CRAFT ion cyclotron heating system has achieved 100% independent intellectual property rights, marking a transition from "catching up" to "leading" in high-power RF heating technology [7] - The prototype component of the highest thermal load divertor has passed acceptance, with a steady-state thermal load capacity reaching 20 megawatts per square meter, indicating China's independent control in divertor research and development [8] - The procurement package for the ITER correction field coils has been completed and delivered after 15 years, signifying a leap in China's superconducting magnet engineering capabilities [9] Group 4 - High and low-temperature hybrid superconducting magnets have achieved a maximum steady-state magnetic field of 35.1 Tesla, overcoming multiple technical challenges under low-temperature high-field conditions, with 100% independent control over materials, processes, and production [10]
