受控核聚变研究目前的重点除了努力在托卡马克类装置中达到点火外,就是探索实现受控核聚变的新途径。美国普林斯顿大学的 S-1球马克就是一个不同于托卡马克的新型的磁约束装置。S-1球马克装置的真空室的直径为320厘米,体积为9650升, The current focus of controlled nuclear fusion research, except in an effort to achieve ignition in tokamak-type devices, is to explore new ways of achieving controlled nuclear fusion. The S-1 ball mark at Princeton University in the United States is a new type of magnetic restraint that is different from the Tokamak. S-1 ball mark the vacuum chamber device is 320 cm in diameter, a volume of 9650 liters,
