论文摘要
我们提出了一项模拟研究，以表征在次级发射产率（SEY）的背景下，Fermilab（FNAL）回收者的稳定性区域。电子与光束管道材料之间的相互作用会产生电子云，从而在某些聚焦构型中危及光束稳定性。回收商记录了这种不稳定，此处介绍的工作反映了改进，以更好地了解这一发现。我们将Furman-Pivi模型纳入了PyeCloud分析中，并确定了鉴于各种束长度，强度，SEY幅度和模型参数的不稳定性阈值。
We present a simulation study to characterize the stability region of the Fermilab (FNAL) Recycler in the context of secondary emission yield (SEY). Interactions between electrons and beam pipe material can produce electron clouds that jeopardize beam stability in certain focusing configurations. Such an instability was documented in the Recycler, and the work presented here reflects improvements to better understand that finding. We incorporated the Furman-Pivi Model into a PyECLOUD analysis, and we determined the instability threshold given various bunch lengths, intensities, SEY magnitudes, and model parameters.
