The Large Hadron Electron Collider (LHeC) is a proposed facility which will exploit the LHC heavy ion beam for electron-nucleus scattering, using a new 60 GeV electron accelerator. The kinematic coverage extends beyond previous deep inelastic lepton-ion experiments by nearly four orders of magnitude at low Bjorken-x and towards higher Q^2. This contribution summarises the content of the simulations in the Conceptual Design report, plus its relation with the LHC with emphasis on pPb data, and the outlook towards a Technical Design report for 2015. After an introduction on the open problems in pA and eA collisions and the expected impact on the heavy ion program, we show inclusive observables and the resulting constraints on nuclear parton densities. We then analyse the possibilities for inclusive and exclusive diffraction and the opportunities that they offer to reveal the non-linear dynamics which tame the low-x growth of parton densities. Finally, we discuss semi-inclusive measurements that will clarify the mechanism of hadronisation and QCD radiation inside the nuclear medium.
