  A polarization control experiment using a pair of crossed undulators has bee proposed for the Shanghai deep ultraviolet free electron laser (FEL) test facility. Numerical simulation indicates that, with the phase-shifter between the two crossed undulators, Fourier-Transform-Limited output radiation with 100nJ order pulse energy, 5ps full pulse length and circular polarization degree above 90% could be achieved. The physical design study and the experimental setup status are presented in the paper.
