A radioactive ion beam facility, GIRAFFE, has been built at the CIAE HI-13 Tandem accelerator. The facility makes use of the inverse kinematics. A D-Q-Q type magnetic separation and focusing system was used in the beam line. This simple device is expected to yield some radioactive ion beams(A<20) near the β-stability line with the acceptable intensities(10 5 -10 6 pps). The ion beams of 7 Be, 1 1 C and 1 7 F were delivered, and the 7 Be beam was applied for two experiments.
