平衡自場對有線性擺動器的自由電子激光器的自發(fā)輻射和受激輻射的影響
THE INFLUENCE OF EQUILIBRIUM SELF-FIELDS ON THE SPONTANEOUS EMISSION AND STIMULATED EMISSION OF FEL WITH A LINEARLY POLARIZED WIGGLER
-
摘要: 本文計算了在平衡自場、線性擺動器場和軸向磁場作用下的電子軌道,并由此求得有線性擺動器的自由電子激光器的自發(fā)輻射和受激輻射。結(jié)果表明自場有增強輻射的作用。

Abstract: 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. -
