Potential of variable polarizing undulators as afterburners — •Julian Gethmann1, Sebastian C. Richter1,2, Axel Bernhard1, and Anke-Susanne Müller1 — 1LAS, KIT, Karlsruhe — 2CERN, Geneva
As part of the EU funded Compact Light project, pros and cons of superconducting undulators with variable polarisation as afterburners for compact Free-Electron Lasers are discussed. For Free-Electron Lasers that use superconducting undulators for compactness, afterburners are the most promising way to provide variable polarized light. Until now, afterburners only exist as permanent magnet undulators which might limit the advantages of using superconducting undulators as main amplifiers in Free-Electron Lasers. However, variably polarizing superconducting undulators have been shown to be feasible. In this contribution we discuss the findings of our simulations and parameter studies exploring the potential of superconducting variably polarizing undulators as afterburners for compact Free-Electron Lasers.
