Description

The variable polarization afterburner at the European XFEL was successfully commissioned in early 2024. It consists of four APPLE-X undulators installed behind the SASE3 planar undulator system, generating the free-electron laser pulses for the soft X-ray beam lines. Various experiments have been conducted with the afterburner since then. These include experiments for users as well as experiments to improve lasing quality and explore new ideas for operating the facility. An overview of these experiments is presented in this report.
