The instability caused beam loss, which limited the stored beam current to be about 600 mA during beam stacking with electron cooling. A vertical feedback damping system (VFS) using an electro-static beam position monitor (ESBPM) and a vertical kicker was applied to suppress this beam instability. The VFS realized not only suppressing the vertical coherent instability, but also revealing the characteristics of the feedback damping.}, pages = {L1307--L1310}, title = {Feedback Damping of a Coherent Instability at Small-Laser Equipped Storage Ring, S-LSR}, volume = {45}, year = {2006} }
