| Abstract | The Super-AC0 UV FEL is used for applications such as a time-resolved fluorescence in biology [I] and two colors expertments (EEL + Synchrotron Radiation). For the purpose of charactenzing and stabilizing the FEL for these users’ experiments, we studied temporal and spectral behaviors of the laser micropulse under the various conditions of synchronization between a positron bunch and an optical pulse. A deformation of a temporal distribution of the laser micropulse, a drift of the lasing wavelength and a spectral evolution are observed. The preliminary results of simultaneous temporal and spectral measurements are obtained. Finally, a longitudinal feedback system is developed to keep the perfect synchronization between the positron bunch and the optical pulse. 1. |
