  Dalian Coherent Light Source (DCLS), which will focus on the Physical Chemistry with time-resolved pump-probe experiments and EUV absorption spectroscopy techniques, is the first high gain FEL user facility in China. The 300MeV linac consists of a laser-driven rf-gun followed by 7 Sband accelerating tubes. A magnetic chicane is adopted to get the desired 300A peak current. After 5 months component installation, first photoelectrons were generated on 17 August 2016. In this paper, we give a summary of the commissioning experience and the beam parameters measurements. In addition, beam jitter sources are studied based on real machine performances.

  FEL operations foresee stringent requirements for the stability of the global linac output parameters and this requirement is particularly stringent for the successful operation of an externally seeded FEL. In order to understand the sensitivity of these parameters to jitters of various error sources along the SXFEL linac, studies have been performed based on analytical methods and tracking code simulations. Using the tolerance budget as guidance, beam jitter control techniques are discussed on the view of the beam dynamics.

Shanghai Soft X-Ray Free Electron Laser (SXFEL) adopts C-band structure to accelerate the electron to 1.5-GeV. Due to high gradient operation, the electric breakdown and structure conditioning problems need to be perfectly resolved. For this purpose, we develop an automatic conditioning control and electric breakdown data acquisition system. The control based on a PXI Express (PXIe) embedded frame and the LabView-FPGA technique. The prototype system design, the software programming and hardware test will be introduced. The experiment setup and test results for a low-level signal will be shown.
