THE INFLUENCE OF EQUILIBRIUM SELF-FIELDS ON THE SPONTANEOUS EMISSION AND STIMULATED EMISSION OF FEL WITH A LINEARLY POLARIZED WIGGLER
平衡自场对有线性摆动器的自由电子激光器的自发辐射和受激辐射的影响

The orbits of an electron in self-fields, linear wiggler and axial fields are calculated. Then the spontaneous emission coefficient and the growth rate of the stimulated scattering are obtained. The numerical results show that under some conditions the selffields can enhance the radiation.
