Description
The precise synchronization between the optical laser and the FEL is of importance for the ultrafast pump-probe experiments. For this purpose, two techniques have been developed at SACLA. One is arrival timing monitors for the hard and the soft X-ray FEL beamlines, which have ~4 fs temporal resolution. The other is a new synchronization system, which consists of a mode-locked oscillator combined with a balanced optical-microwave phase detector (BOM-PD). The typical arrival timing jitter of the new system is ~40 fs (RMS). In this presentation, we will report the recent status of the synchronization system at SACLA.
