公元2000年时,正在积极研究的可控热核聚变,可能会在各种微波管的协助下提供商用电力。等离子体在产生核聚变前,必须加热到极高的温度(摄氏一亿度,为太阳表面温度的五倍)。多种微波管可用来加热等离子体,但每一种应用都要与 In the year 2000, the actively controlled thermonuclear fusion, which is under active investigation, may provide commercial power with the help of various microwave tubes. The plasma must be heated to very high temperatures (100 million degrees Celsius, five times the solar surface temperature) before nuclear fusion occurs. A variety of microwave tubes can be used to heat the plasma, but for every application
