The Vacuum System for SDUV FEL Experiment Facility

Among different approaches towards next generation light source, Free Electron Laser (FEL) is a promising candidate for its excellent light performance and engineering feasibility. SDUV FEL (Shanghai Deep Ultraviolet Free Electron Laser) is a test facility in the Shanghai Institute of Applied Physics (SINAP), Chinese Academy of Sciences. First FEL commissioning was conducted in 2009, and preliminary experiment was conducted. In this paper, the vacuum system of facility is described, including overview layout, subsystem and component design. Some installation and running experience is also presented.
