英文摘要	The polarization switch of a free-electron laser (FEL) is of great importance to the user scientific community. In this paper,we investigate the generation of controllable polarization FEL from two well-known approaches for Dalian coherent light source,i.e.,crossed planar undulator and elliptical permanent undulator. In order to perform a fair comparative study,a one-dimensional time-dependent FEL code has been developed,in which the imperfection effects of an elliptical permanent undulator are taken into account. Comprehensive simulation results indicate that the residual beam energy chirp and the intrinsic FEL gain may contribute to the degradation of the polarization performance for the crossed planar undulator. The elliptical permanent undulator is not very sensitive to the undulator errors and beam imperfections. Meanwhile,with proper configurations of the main planar undulators and additional elliptical permanent undulator section,circular polarized FEL with pulse energy exceeding 100 uJ could be achieved at Dalian coherent light source.
