Abstract :
Prior to the 1995 shutdown of the ELSA facility, we recorded our first time-resolved photon spectra. They clearly showed the chaotic behaviour predicted at high coupling but their low signal-to-noise and time resolution precluded a fine analysis. A new high-sensitivity, high-speed spectrometer should overcome these limits. We also successfully tested a new device based on secondary emission to acquire time-resolved electron spectra and we made preliminary tests of the 60-parameters-on-line tapering of the TRIA wiggler. The facility is to be run again at the end of the year with an improved level of performance and reliability.
