Abstract：
The Experiment of RF modulation at the HLS(Hefei Light Source) is introduced. The 4%—8% AM(Amplitude Modulation) or the 2°—3° PM(Phase Modulation) with the modulated frequency closed to the longitudinal synchrotron oscillation frequency improves the beam lifetime. The experiment also finds out the intensity of the beam spectrum reduced after applying the RF modulation, which shows that the modulation is useful for suppressing the coupled-bunch instability.
