.Synchrotron radiation (SR) is a unique high-brightness and fully polarized light source.
However, typical insertion devices supply only linearly polarized radiation, precluding
studies of chiral dynamics and spin structures. To fulfill a strong demand for circularly
polarized radiation, an elliptically polarized undulator (EPU) provides the greatest
merit flux and thus has become the...
