The 4 electrode signals of the beam position detector(BPM) of the STORAGEring of HEFEI Light Source are directly connected to the domestic oscilloscopewith 12bit resolution, 10Gsps sampling rate and 2GHz bandwidth. The acquisitionprogram is run on the cloud host under the Zstack architecture, triggering toread a group of waveforms of 500us each time. The X (horizontal position), Y(vertical position) and Z (longitudinal phase) information of the centroid of45 bunches 2266 cycles were extracted. The resolution of X and Y of eachbunches was about 5um, and the resolution of Z was about 0.5ps. The updateperiod of online operation was about 7 seconds. The three-dimensional tune ofeach bunch can be obtained by analyzing the three-dimensional positioninformation of each bunch in normal operation. The spectrum peak of thetransverse quadrupole oscillation can be observed by analyzing the button andstrip electrode signals when beam is incentived.

Hefei light source storage ring bunch by bunch 3D position measuring system is introduced and a preliminary study is shown
