Abstract：
During the commissioning and early operation of the upgraded BEPCⅡ injector linac, some beam instabilities were appeared, and have been studied by both experimental and analytical ways. This paper describes the observed beam orbit instabilities, beam energy jitter, and the beam emittance jitter. The ways to cure these instabilities are also presented.
