	The Radiation Source ELBE at Helmholtz-Zentrum Dresden-Rossendorf is currently extended to offer capacity for new experiments. The reconstruction includes the setup of a THz-beamline with a dedicated user laboratory and a beamline for electron-beam - high-power laser experiments. The current synchronization scheme offers stability to the picoseconds level. The new experiments require a femtosecond synchronization in order to get field-strength resolved THz-probes and to have a stable overlap between the electron-bunches with the laser pulses. In the future there will be a MIT/DESY-like system [1] with a pulsed fiber laser as an optical reference oscillator. The laser pulses will be distributed over stabilized fiber links to the remote stations. Later on it is planned to install EOM-based beam arrival time monitors (BAMs) in order to monitor the bunch jitter and to establish a feedback system to reduce the jitter. Besides that, the timing system has to be revised to trigger experiments with low repetition rate, two guns (thermionic DC, superconducting RF) and lasers. The Poster will show the Layout of the possible future Timing and Synchronization System at ELBE. [1] J. Kim, J.A. Cox, J.J. Chen, F.X.

The Radiation Source ELBE at Helmholtz-Zentrum Dresden-Rossendorf is currently extended to offer capacity for new experiments. The reconstruction includes the setup of a THz-beamline with a dedicated user laboratory and a beamline for electron-beam - high-power laser experiments. The current synchronization scheme offers stability to the picoseconds level.
