数字束流位置信号处理算法优化
Optimization of signal processing algorithm for digital beam position monitor
摘要
Abstract
Based on turn-by-turn (TBT) signal processing, the paper emphasizes on the optimization of system timing and implementation of digital automatic gain control, slow application (SA) modules. Beam position including TBT, fast application (FA) and SA data can be acquired. On-line evaluation on Shanghai Synchrotron Radiation Facility (SSRF) shows that the processor is able to get the multi-rate position data which contain true beam movements. When the storage ring is 174 mA and 500 bunches filled, the resolutions of TBT data, FA data and SA data achieve 0. 84, 0. 44 and 0. 23 μm respectively. The above results prove that the design could meet the performance requirements.关键词
