Abstract
In this paper the use of betatron radiation as a seed for the Free Electron Laser (FEL) is presented. The scheme shown can be adopted from all FEL driven by plasma accelerated electron beams via Particle or Laser Wake Field Acceleration. Intense radiation in the region of X ray characterized by a broad spectrum, the betatron radiation, is indeed produced in the plasma acceleration process from the electron passing through the ionized gas. It is proposed to use this radiation, suitably selected in wavelength and properly synchronized, to stimulate the emission of the Free Electron Laser.
