	A compact, high-power, narrowband, tunable coherent light source in THz regime will be a quite useful tool for bimolecular science and advanced imaging for security and so on. In this work, we propose a compact seeded THz (frequency:0.5 – 2 THz) high-gain single pass free electron laser (FEL) amplifier using a multi-bunch photocathode RF gun* and a compact hybrid staggered undulator and injection-seeded terahertz parametric generator (IS-TPG). The proposed configuration has following advantages: 1. The Fourier transform limit of the THz seeded pulse can overcome the disadvantage of broad spectrum of a self-amplified spontaneous emission (SASE). 2. The resonant FEL wavelength can be rapidly controlled by changing solenoid current of the staggered undulator. 3. The single pass configuration without optical cavity mirrors helps to achieve the rapid frequency tuning. In the conference, the detailed design and numerical estimation will be discussed. R.
