Abstract

The kink instability presents one of the limiting factors from achieving higher luminosity in an ERL based electron ion collider (EIC). We present two possible dedicated feedback systems to suppress the instability, both of which benefit from the latest development of beam instrumentation. The first takes advantage of the flexibility of the linac-ring scheme to adjust the initial condition of the electron beam; the second uses a pickup and kicker setup with proper bandwidth on the ion ring. Both schemes raise the threshold of the kink instability dramatically and provide opportunities for higher luminosity. We studied the effectiveness of the systems and their dependence on the feedback parameters and beam parameters.
