The luminosity of the ring-ring version of the proposed electron-ion collider eRHIC is limited by the beam-beam effect on the electrons.Once the beam-beam limit is reached, the luminosity no longer Baby Tee increases linearly with the bunch intensity of the ion beam, but begins to saturate and even drops again if the beam-beam tuneshift is increased further.To overcome Wooden Dollhouse this limitation we investigate a compensation scheme with an electron lens acting on the electron beam.Using weak-strong simulations we find a possible luminosity increase of about a factor 2.
