Placet based start-to-end simulations of the ILC with intra-train fast feedback system

Integrated simulations are important to assess the reliability of the luminosity performance of the future linear colliders. In this paper we present multi-bunch tracking simulation results for the International Linear Collider (ILC) from the start of the linac to the interaction point. The tracking along the linac and the beam delivery system is done using the code PLACET. This code allows us to introduce cavity wakefield effects, element misalignment errors and ground motion. Static beam based alignment of the linac is also considered. The luminosity and beam-beam parameters are calculated using the code GUINEA-PIG. In the framework of the Feedback On Nano-second Timescales (FONT) project, we describe and simulate an updated fast intra-train feedback system in order to correct for luminosity degradation mainly due to high frequency ground motion
