Quantum Theory of Generation of Coherent XRay in a Wiggler
Abstract
In this paper we present the nonlinear quantum theory of XRay FEL in a wiggler. We present the solution of the Dirac equation in a space periodic strong magnetic field, which describes the quantum dynamics of a single electron in a wiggler. With the help of obtained wave function of an electron the selfconsistent set of the Maxwell and relativistic quantum kinetic equations is obtained. Then, the process of coherent Xray radiation generation in nonlinear quantum regime, when the photon energy is larger than resonance widths due to energetic/angular spreads of an electron beam and resonance width caused by finite interaction length, is investigated.
