Segmented Elliptical polarization undulators (EPUs) and a phase shifter are constructed in a double mini-beta function lattice for a high brilliance soft X-ray at Taiwan Photon Source (TPS). The performance of the radiation in terms of brilliance and transverse coherence properties is calculated based on the statistical optics. The work also shows the performance of EPUs and a phase shifter.
