| Abstract: | In this paper, we introduce the Bunch-by-bunch tracing-measurement system in HLS, and describe some results of experiments and analyses. Using an in-phase gate signal for simulating beam signal and a frequency divided signal of RF for supplying external trigger of ADC, we test the reliability and the stability of this system. By this system, we trace and record a full process of injection, ramping, RF decreasing, closed orbit correcting, wiggler charging, adding skew-quadrupole and opening for users. The tune shift and the coupled bunch instability during the full process have been shown in the end. |
