Ion driven effects in the intense electron beam circulating in storage rings

Ion-driven effects in electron beams impose severe limitations on performance of storage rings. These effects are much similar to the well-studied effects of the beam space charge. Most effects caused by the entire charge of the beam can be calculated by commonly used codes, e.g., BeamParam and ZAP. We make an attempt to survey briefly in this report the scaling coefficients of the ion-driven effects related to those of the beam charge.
