Title Polarization analysis for seeded FELs in a crossed-planar undulator
Abstract The crossed-planar undulator is a promising scheme for full polarization control in x-ray FELs. For SASE FELs, it has been shown a maximum degree of circular polarization of about 80% is achievable at fundamental wavelength just before saturation. In this paper, we study the effectiveness of a crossed undulator for a seeded x-ray FEL. The degree of circular polarization for both the fundamental and the harmonic radiation are considered. Simulations with realistic beam distributions show that a degree of over 90% and 80% is obtainable at the fundamental and 2nd harmonic frequencies, respectively.
