论文摘要
在本文中，提出了Betatron辐射作为游离电子激光（FEL）的种子。可以通过粒子或激光唤醒场加速度来驱动的所有FEL采用该方案。以宽光谱为特征的X射线区域中的强烈辐射确实是由于通过电离气体的电子而在等离子体加速过程中产生的。建议使用这种辐射，适当地在波长中选择并正确同步，以刺激游离电子激光的发射。
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.
