Tapered wiggler technique used in Raman PEL of low energy electron beam
The expressions of extraction efficiency are deduced by means of ponderomo-tive potential, the actions of tapeied wiggler technique on efficiency enhancement lasers are analysed, and the experiment of FEL with tapered wiggler intensity of magnetic field has been conducted by this technique, the result indicates that itsefficiency is 2.6 times that of FEL with constant wiggler intensity of magnetic field.
