Abstract：
THz radiation lying in the region between the microwaves and the infrared, with the property of high spatial resolution and low quantum energy, has wide applications. However, lacking of proper THz source has greatly delaying the related THz science and technology development. Peking University plans to construct a facility of THz source using the DC-SC superconducting accelerator. It is based on coherent undulator radiation. The source has the property of high peak power, high average power, high coherence, high repetition rate and tunable wavelength between 660—1200μm. The facility will provider a powerful tool for the research of biology, medicine, material, telecommunication and so on. This paper gives a brief description about the design considerations and an estimation on the property of the THz source.
