对两个用于核聚变研究的装置将投入50亿美元以上的资金。美国的“国家点火装置”项目投资约为30亿美元,法国的“兆焦耳激光器”投资约为21亿美元。两个项目的均计划在本10年的年底前完成。 这两个项目为达到同一目标而建造:获得惯性约束聚变。两国的科学家都在建造产生1.8MJ脉冲的激光器。将此激光打在金靶上,可产生X射线,压缩氘氘燃料靶丸,产生聚变,释放更多的能量。然而这一任务极其复杂,光是它们使用的光学元件就在30000个以上。 在美国劳伦斯·里弗莫尔国家实验室,容纳“国家点火装置”的大楼已开始建成。同时,在法国波尔多市的郊区,法国原子能局 More than $ 5 billion will be invested in two devices for nuclear fusion research. The U.S. “national ignition” project invested about 3 billion U.S. dollars and the French “MJL” invested about 2.1 billion U.S. dollars. Both projects are planned to be completed by the end of this decade. These two projects are built to achieve the same goal: to obtain inertial confinement fusion. Scientists in both countries are building lasers that generate 1.8 MJ pulses. Placing this laser on a gold target produces X-rays, compressing deuterium-deuterium fuel pellets, creating fusion and releasing more energy. However, this task is extremely complex, just because they use more than 30,000 optical components. At Lawrence Livermore National Laboratory in the United States, the building containing the “national ignition” has begun. At the same time, in the suburbs of Bordeaux, France, the French Atomic Energy Agency
