The ions trapped by beam potential well can cause beaminstability in electron storage rings.
在电子储存环中，由于被束流势阱俘获的离子会引起束流不稳定性。

In addition, it required to measure and analyze the beam spectrum while the experiments of accelerator physics and study on the beaminstability are made.
另外在加速器物理实验以及在研究各种束流不稳定性的机器研究过程中，都需要频谱测量和频谱分析。
