      abstract     = {At the European XFEL, two undulator systems for hard and
                      one for soft X-rays have been successfully put into
                      operation. The SASE3 soft X-ray undulator system generates
                      linearly polarized radiation in the horizontal plane. One of
                      the requirements for extending the radiation characteristics
                      is the ability to obtain different polarization modes. These
                      include both right and left circular, elliptical
                      polarization, or linear polarization at an arbitrary angle.
                      For this purpose, a system consisting of four APPLE X
                      helical undulators developed at the Paul Scherrer Institute
                      (PSI) is used. This paper presents the design parameters of
                      the SASE3 undulator system after modifying it with the
                      helical afterburner. It also describes the methods and the
                      design solutions different from those used at PSI. The
                      status and schedule of the project are introduced.},
