多年来,科学家都想在实验中以可控的方式驯服热核聚变———星体产生能量的过程,因为聚变能发电厂可能产生清洁无害而又无穷无尽的能量。在聚变反应中,两个轻氦收缩在一起,直到它们产生反应,形成一个较重的核子。例如,氢的重同位素———氘和氚就可以产生反应,形成一个氦核和一 For years, scientists wanted to tame thermonuclear fusion in a controlled manner during experiments - the process by which the stars generate energy, because of the clean, innocuous but inexhaustible energy that fusion power plants can produce. In a fusion reaction, two light heliums shrink until they react to form a heavier nucleus. For example, heavy hydrogen isotopes - deuterium and tritium can react to form a helium core and a
