Beam-beam simulations for future electron-ion collider eRHIC

The future electron-ion collider eRHIC - under design at BNL - will collide the electron beam accelerated in energy recovery linacs with protons or ions circulating in the RHIC storage ring. The beam-beam effects in the linac-ring configuration have a number of unique features. For the in-depth studies of the beam-beam effects and the resulting luminosity limitations, we developed a dedicated simulation code. We studied the effects of the mismatch, the disruption and the pinching on the electron beam. Relevant dynamics of the proton beam, including the kink instability in combination with incoherent beam-beam effects, was also explored in detail. In this paper we describe the main features of our simulation code and present the most important simulations results.
