Stationary parameters of a neutralized electron cooling system

The stationary parameters of a neutralized electron cooling system (the electron current, the neutralization degree, etc.) are defined by an energy balance equation for the ions. We discuss the main sources of the ion heating: incoherent heating (natural and artificial) as well as coherent heating due to dipole oscillations excited by an interaction between the primary electrons and the ions. Analysis of beam lifetime with account of this energy balance equation and maxwellization due to intrabeam scattering permits us to estimate the stationary parameters. Results of estimations are compared with experimental data obtained at the LEAR e-cooling system.
