Abstract In the FEL experiment, when electron beam passes through the wiggler, the movement of electron beam will be changed to wiggle in the wiggler due to the periodical magnet field. Meanwhile the electron beam will spontaneously emit the radiation with a wavelength similiar to the FEL radiation. This radiation is influenced by the parameters of both the electron beam and the wiggler. The gain of FEL was determined by the spontaneous emission spectrometer, and the spectrum width mainly determined by the periods of wiggler and electron energy homogeneity (ΔE/E). According to the measured parameters of electron beam and the wiggler, the spontaneous emission was studied. In the experiment, the spectrum of the spontaneous emission was measured by far infrared 100 μm spectrometer with Ge∶Ga detector.
