世界最大激光器、被称为“人造太阳”的美国国家点火装置(NIF)正距离其目标越来越近,显示了一个可持续核聚变反应装置正在由梦想逐步成为现实。NIF融合了美国多家实验室的心血,迄今仍无人能挑战其世界上最大激光聚变机器的地位。在不久前的一次“点火”中,NIF以接近太阳中心的温度对原子进行加热,使目标物的最外层发生爆炸。在强烈内爆力的驱使下,内部燃料瞬间压缩,形成冲击波,进一步加热中心区域的燃料,导致可持续性燃烧, The United States National Ignition Facility (NIF), the world’s largest laser, known as the “artificial sun,” is getting closer and closer to its goal, showing that a sustainable fusion reactor is gradually being realized from a dream. NIF combines the efforts of many laboratories in the United States, so far no one can challenge the world’s largest laser fusion machine status. In a recent “ignition”, the NIF heated the atom close to the center of the sun, causing the outermost layer of the target to explode. Driven by a strong implosion, the internal fuel instantly compresses to form a shock wave, further heating the fuel in the central area, resulting in a sustainable combustion,
