Abstract
Storage ring free electron lasers have a complex dynamics as compared to th e LINAC driven FEL sources since both the laser and the recirculating elect ron beam behaviours are involved. Electron beam perturbations can strongly affect the FEL operation (start-up, stability) whereas the FEL can stabiliz e beam instabilities. Experimental analysis together with simulations are r eported here. Improvements of the Super-ACO FEL for users is discussed, and consequences are given in terms of electron beam tolerances for a source d evelopment for users. (C) 1999 Elsevier Science B.V.
