用束流位置监测器测量上海光源束流寿命
Beam lifetime measurement using beam position monitor in SSRF
摘要
Abstract
The output signal of beam position monitor (BPM) carries not only position information but also charge information. It can reflect the changes of the beam charge and be used for beam lifetime measurement. In this paper, the feasibility of beam lifetime measurement using BPM was investigated through theoretical analysis. Some experiments were conducted on the storage ring of Shanghai Synchrotron Radiation Facility(SSRF) to evaluate the performance. Compared with the DC current transformer( DCCT) system, the lifetime measured by BPM has higher data rate and resolution. It is useful for the beam lifetime evaluation of different time scales and the measurement accuracy can be further improved by averaging the results of multiple BPMs.关键词
