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 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 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. This article is available under the terms of the Creative Commons Attribution 3.0 License.
