According to the energy conservation, the maximum electron efficiency is evaluated either with or without the relativistic effect . the result shows that the efficiency to translate the energy from dc field to rf field will increase with the increase of input voltage to some degree 最后,我們從能量的觀(guān)點(diǎn)出發(fā)推導(dǎo)出milo的最大電子效率及相對(duì)論效應(yīng)對(duì)電子效率的影響,得到的結(jié)果表明在一定程度上提高輸入電壓可以提高電子將直流場(chǎng)能轉(zhuǎn)換為交流場(chǎng)能的效率。
