摘　　要：数字束流位置处理器Libera可以直接用来测量宽带的束流位置信号,由于其出色的硬件和软件性能,它可以在束流参数测量与诊断中得到广泛的应用。文章介绍了利用Libera在BEPCII储存环上进行的一些实验:利用逐圈(Turn-by-turn)束流位置测量数据计算横向阻尼时间和测量注入冲击磁铁引起的束流位置残余振荡,实验主要目的是使BEPCII储存环的束流调试和参数优化更方便快捷,并取得了初步的成效。The digital beam position monitor （BPM） signal processing electronics - Libera is a commercial product that can offer superior performance with multiple measurement channels delivering simultaneously position measurements in digital format with MHz, KHz and Hz bandwidths. It is widely used in the beam diagnostics system. In this paper, we introduced a series of experiments with respect to residual orbit oscillation and damping time measurements by using Libera in the BEPCII storage ring. The interesting experiment results are also given.
