The ion core density in electron storage rings with clearing electrodes

The low density of the ion core is required for efficient performance of electron storage rings. One of the effective methods of decreasing the density of ions in the electron beams circulating in storage rings is the application of electrostatic clearing electrodes. This report presents the results of analytic investigations of the ion core density distribution versus the magnetic field, the beam current, the density of the residual gas in the vacuum chamber and the distance between the sequential clearing sets. The numerical simulation of self-consistent evolution of the ion core has also been carried out. The results of simulation are in agreement with the theoretical predictions
