Abstract The superconducting linac of China Accelerator-Driven System Injector II will operate at CW-mode. The mechanical vibrations of the superconducting cavity, also known as microphonics, cause shifts in the resonant frequency of the cavity. The microphonics is the main disturbance source of cavity frequency shifts when the cavity running in CW mode. In order to understand the effects, microphonics measurements were performed on the half-wave superconducting cavities when they were operated in the cryostat. And the experimental modal test was also performed to identify noise source and improve the cavity structure optimization. The measurement method and results will be shown and analyzed in this paper.
