摘　　要：在合肥光源(HLS)升级改造中,为了增强注入器的束流位置检测器(BPM)系统的整体性能,采用单次通过数字束流位置处理器(Libera Brilliance Single Pass)构成信号处理系统。首先对Libera BrillianceSingle Pass进行了离线的性能测试,然后用它对条带BPM进行实验台标定,最后在合肥光源现有200MeV直线加速器上进行了在线测试。结果显示其离线分辨力为4～17μm,优于原有对数比处理系统。在线水平和垂直分辨力分别好于26μm和19μm,优于原有系统的58μm和33μm。In the upgrade of Hefei Light Source（HLS）,Libera Brilliance Single Pass is chosen to constitute a signal processing system in order to enhance the overall performance of the injector beam position monitor（BPM） system.The characterization test of the apparatus was made.The mapping of stripline BPM was carried out on a workbench with Libera Brilliance Single Pass.The beam position was tested at HLS＇s existing 200 MeV linear accelerator using Libera Brilliance Single Pass.The results show that the offline resolution is 4 μm to 17 μm,better than that of the original logarithmic processing system.The online horizontal and vertical resolution is better than 26 μm and 19 μm,respectively,also better than the existing system＇s 58 μm and 33 μm.
