Small-x physics opportunities with a large hadron-electron collider at CERN.

I discuss the possibilities for small-x physics studies offered by the proposed electron-proton and ion collider at CERN, the Large Hadron-electron Collider. After a short introduction on open problems at small x, I focus on small-x aspects in both ep and eA, first on inclusive measurements and then on diffraction. I finish by discussing some opportunities for final state and photoproduction studies. [ABSTRACT FROM AUTHOR]
