数字束流位置处理器Libera可直接用于测量宽带束流位置信号,在束流参数测量与诊断中得到广泛应用。本工作利用Libera在合肥光源储存环上完成了工作点、相空间和横向振荡阻尼时间常数等的测量,并给出测量结果。
Digital beam position monitor Libera is able to acquire wide-band beam position signal. Libera can be used in multifarious applications of beam diagnoses due to its standout performance. In present work, betatron tune, phase-space and damping time constant were measured using Libera, and the measured results were given.
