| In this paper the trajectory of electron in a free-electron laser (FEL) with modified planar wiggler is analyzed using single particle dynamics. It is shown that the new odd harmonics are generated due to the transverse oscillations of electron in the wiggler frequency and its harmonics. Spontaneous emission of modified FEL is calculated analytically and possibility of emission at up-shifted wiggler frequency and their odd harmonics has been found. After that by calculating the spontaneous emission numerically, we show that peaks of spontaneous emission spectrum are in good agreement with analytical calculations. |
