Abstract
We show that Free Electron Lasers (FEL) operating with storage rings may co unteract beam instabilities of the Saw Tooth (STI) type. We use a model bas ed on a set of equations that couple those describing the FEL evolution to those accounting for the STI dynamics. The analysis provides a clear pictur e of the FEL-STI mutual feedback and clarifies the mechanisms of the instab ility inhibition. The reliability of the results is supported by a comparis on with fully numerical codes. (C) 1999 Elsevier Science B.V. All rights re served.
