Abstract :
The instabilities produced by ions are one of the issues in the electron storage ring. At SRRC, H2 ion is the dominate species. Comparing with other species, H2 ions are difficult to trap from the conventional ion points of view for its small atomic mass. H2 ions could introduce fast beam ion instabilities. In order to understand more details of the ion produced instabilities in the ring, H2 gas was intentionally vented into the ring chamber. In this paper, the instabilities which relate to the H2 ions are described and the physics is also discussed
