Simulations of an Intra-Pulse Interaction Point Feedback for NLC

Abstract

Position and angle jitter of the beams at the interaction point are important sources of luminosity degradation in future linear colliders. In order to reduce their effect, intra-pulse feedbacks can be used. Some simulations are presented to evaluate a position feedback at the interaction point. The influence of angle jitter onto this feedback are investigated and possible fixes are discussed. A feedback is proposed that allows to also reduce the effect of angle jitter
