N2 - High-gain FEL is one of many electron-beam instabilities, which have a number of common features linking the shot noise, the amplification and the saturation. In this paper we present a new, model-independent description of the interplay between these effects and derive a simple formula determining the saturation and maximum attainable gain in such instabilities. Application of this model-independent formula to FELs is compared with FEL theory and simulations. We describe limitations resulting from these findings for FEL amplifiers used for seeded FELs and for Coherent electron Cooling.
