Description

This paper introduces the influence of the Spoke 012 superconducting cavities mounted in China Accelerator Driven sub-critical System (C-ADS) caused by micro-phonics and Lorentz force detuning and the characteristics of the piezo fast tuner for 7# cavity in CM1. The design of the basic frequency-tuning loop and the side-band suppression loop by using the piezo characteristics and the damping technology is also described in details. Both the loops have been used in the commissioning. The former suppresses the low-frequency oscillation effectively and the latter reduces the amplitude of the certain vibration by 15 dB. (authors)
