  The layout of the THz source based on FEL was de-scribed in this paper. The THz source was based on a FEL which was composed of a compact 8-14MeV LINAC, undulator, optical resonance, THz wave measurement system and so on. The facility was designed in 2013 and the typical running parameter got in 2017 were as the following: energy is of 12.7MeV, energy spread is of 0.3%, macro-pulse is of 4 μs, pulse length of micro-pulse is of 6ps, emittance is of 24 mm.mrad. After that the ma-chine was commissioning for production THz radiation. In November 2018, the THz wave was test and got THz wave signal, the spectrum was also got. This year, we plan to measure the output power of the THz source.

Accelerator online alignment technology is an important means for accelerator stability detecting. A CCD-based laser alignment detection system is designed for the linear accelerator, and the detection distance of the system could reach 100m. The reference comparison method is used to detect the laser imaging position acquired by the reference detector at different times, and to obtain the relative positional deviation of the measurement reference or the tested objects. Through the measurement error analysis, the precision of the system is expected to reach ±10μm.
