In this paper,we report the development of a bunch-by-bunch beam current acquisition system.Through a waveform-reconstruction algorithm,the system realizes high equivalent sampling rate with a relatively low inherent rate.Based on the EPICS environment,information communication with other systems can be achieved.Preliminary test results in commissioning the SSRF storage ring show that the system can reconstruct the beam waveform of single bunch,providing a convenient and reliable method for the top-up operation in the future.
