	The advancement of superconducting undulator (SCU) technology is of strategic importance for the future development of the European XFEL facility. To build the know-how to implement superconducting undulators for its future upgrades, several projects are ongoing: a prototype SCU module (S-PRESSO) for an afterburner in the hard X-ray undulator line SASE2 is being procured; two test stands (SUNDAE1 and SUNDAE2) for the characterization of SCU are being developed; advanced SCU coils are designed and manufactured in house. In this presentation, we describe the status and plans of those projects and highlight their expected performances.

TH2A1	Dechirper System for Fresh-slice Applications at the European XFEL

	Fresh-slice lasing using dechirper induced time-dependent orbit oscillation is capable of producing high intensity two-color XFEL pulses and high power short pulses at femtosecond level. At the European XFEL, a dechirper system for fresh-slice applications for both the hard x-ray beamline SASE1 and the soft x-ray SASE3 beamline is being developed. In this contribution, we present the novel design of the wakefield structure and initial commissioning efforts.

TH3D2	Radiation Protection Issues in Undulator Upgrades for the European XFEL	245

	European XFEL is the first free electron laser operating at MHz repetition rate with electron beam energy up to 17.5 GeV. The high repetition rate together with the high electron beam energy provides unique opportunities for users in different domains. To further extend the operation schemes, some upgrades have already been implemented and several more are planned. The advanced operation schemes may require devices inserted into the beam like slotted foil or narrow vacuum chambers such as for the corrugated structure, the Apple-X undulator, and the superconducting undulator. Due to the high beam power generated by the superconducting linac, there are concerns about increased radiation loads. Therefore, simulations and measurements have been carried out to study the radiation dose rates that may be generated. We give an overview of the simulations and measurements for the above mentioned schemes.
