[Experimental investigation of CAEP far-infra-red 100 microm FEL spontaneous emission].


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… (More)
