Abstract：
The PKU-SCAF comprises three RF units: the 1.5cell injector which is developed all by ourselves, the upgraded 3.5cell injector, and the 1.3GHz 2×9cell Telsa style main accelerator. To take full advantage of the high quality electron beam of PKU-SCAF, we decide to compress the electron bunch out of 1.5cell injector for coherent THz and the bunch from main accelerator for FEL. For compressing the bunch, we design a chicane compressor with changeable parameter for PKU-SCAF which can serve for the two kinds of compression.
