  The X-ray FEL project at SPring-8 aims to build an X-ray lasing facility, which will generate brilliant coherent X-ray beams with wavelength of below 0.1nm. A combination of short-period in-vacuum undulators and an 8GeV high-gradient C-band linear accelerator makes the machine compact enough to fit into the SPring-8 1km-long beamline space. The machine commissioning will be started by March 2011. We designed the control system for the new machine based on the present SCSS test accelerator, which employs the MADOCA framework. The control system is based on the so-called “standard model” and composed of Linux-based operator consoles, database servers, Gigabit Ethernet, VMEbus system, and so on. The control system, also, has a synchronized data-taking scheme to achieve beam-based optics tuning. Most of the device control part is installed in water-cooled 19in. racks together with RF devices for temperature control, which guarantees stable RF phase control. This paper gives an overview of the project and describes the design of the control system. In addition, we briefly report the status of the SCSS test accelerator operated as a VUV-FEL user facility.
