The Radiation from Curvilinear Electron Beams in Periodical Magnetic Fields

In this paper we have tried to use the concept of working a relativistic laser on free electrons (FEL) that is based on the effect of a magnetic-braking radiation of charge particles moving along curve trajectories. In a region of small particle velocities (much less than the light speed), this concept could be realized with the radiation efficiency being substantially by a considerable deformation of the electron beam trajectory.
