To maintain the luminosity within a few percent of the design value, beam stability at the interaction point (IP) must be controlled at the subnanometer level. To help achieve such control, use of an intra-pulse IP feedback system is planned. With CLIC's very short bunch spacing of 0.5 ns, and nominal pulse duration of 176 ns, this feedback system presents a significant technical challenge. Furthermore, as part of a study to optimize the design of the beam delivery system (BDS), several L∗configurations have been studied. In this paper, we will review the IP feedback simulations for the 380 GeV machine for two L∗configurations, and compare luminosity recovery performance with that of the original L∗configuration in the 3 TeV machine.
