Abstract :
A small angle crab scheme is being considered for the LHC luminosity upgrade. In this paper we present a 400 MHz superconducting cavity design and discuss the pertinent RF challenges. We also present a study on the beam-beam performance and proton-beam emittance growth in the presence of crab compensation, with RF noise sources.
