Zusammenfassung, Abstract
A new device for polarization control at the free electron laser facility FLASH1 at DESY has been commissioned for user operation. The polarizer is based on phase retardation upon reflection off metallic mirrors. Its performance is characterized in three independent measurements and confirms the theoretical predictions of efficient and broadband generation of circularly polarized radiation in the extreme ultraviolet spectral range from 35 eV to 90 eV. The degree of circular polarization reaches up to 90{\%} while maintaining high total transmission values exceeding 30{\%}. The simple design of the device allows straightforward alignment for user operation and rapid switching between left and right circularly polarized radiation.
