Head-on beam-beam compensation investigation in an electron-ion collider using weak-strong simulations

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 ag...
