当前和未来加速器的性能可能会受到电子云（EC）效应的限制。 EC的形成和演变是由加速器真空室的壁面特性决定的。我们提出了总二次电子产额（SEY）的测量结果以及作为入射电子能量函数的二次电子的相关能量分布曲线。由于初级电子能量非常低（
Present and future accelerators' performances may be limited by the electron cloud (EC) effect. The EC formation and evolution are determined by the wall-surface properties of the accelerator vacuum chamber. We present measurements of the total secondary electron yield (SEY) and the related energy distribution curves of the secondary electrons as a function of incident-electron energy. Particular attention has been paid to the emission process due to very low-energy primary electrons (
