Stochastic Description Of Internal Target Effects On Electron-Rings

The effects of internal targets on the beam accumulated in electron storage rings are studied with a linear stochastic model which describes the beam emittance and the beam phase-space growth and provides simple formulae for the longitudinal and transverse beam emittance. The description of facilities with and without beam damping is carried out in a consistent way. The obtained results are comparable to those obtained with other models and numerical simulations.
