Abstract :
Transverse oscillations are observed in the SRRC storage ring as the empty filling gap or the chromaticity is not big enough. The source of transverse oscillations are mostly coming from ions. From experimental evidence the beam quality will be improved as transverse oscillation is suppressed. The RF knockout method is employed to cure the transverse oscillations by shaking at the frequency of betatron sideband. The details of the shaking and the improvement on beam quality are discussed as RF knockout method is applied
