摘要
本文描述了冷却储存环运行过程中得到的一些Schottky信号和束流位置探测器上的信号,这些信号与束流的不稳定性有一定的关系,有些是由于硬件引起的,有些是束流本身产生的,分别给出了注入时、冷却后和冷却力测量过程中离子束中心频率随时间的变化,分析了产生这些现象的原因,尝试寻找解决的方法,以期提高束流的稳定性,为下一步Schottky质量测量实验做准备.
Some signal samples acquired from Schottky probes and beam position monitor during operation were presented in this paper, and they were observed in the different operation periods such as during injection, after cooling and cooling force measurement. These signals were considered related with the ion beam instability. The central frequency of ion beam varied with the time. Some were caused by the ripple of hardware, others were created by ion beam itself. The reasons which caused these phenomena were analyzed. The possible solutions were suggested, and some necessary upgrade and improvements were expected. These results were helpful to attempt the Schottky Mass Spectrometry measurement in the CSR.
