AURORA exhibits negligible dispersion and supports broad spectral operation. It is remotely controllable and vacuum-compatible.\u003c\/p\u003e\n\u003cp\u003eThe outstanding dispersion properties and minimal change to the delay line make AURORA perfectly suited for ultrafast and attosecond XUV sources, including high-harmonic generation (HHG) beamlines. The supported energy ranges include important absorption edges of transition metals (Fe, Co, Ni), enabling magnetic circular dichroism (MCD) experiments in materials science.\u003c\/p\u003e\n\u003ch3\u003eKey Product Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eXUV quarter waveplate: generates circularly-polarized XUV without added dispersion — ideal for attosecond experiments\u003c\/li\u003e\n\u003cli\u003eUp to ~40% max transmission (40-85 eV version) \/ ~30% (10-40 eV version)\u003c\/li\u003e\n\u003cli\u003eTwo spectral-range versions: \u003cstrong\u003eLow-energy 10-40 eV\u003c\/strong\u003e and \u003cstrong\u003eHigh-energy 40-85 eV\u003c\/strong\u003e\n\u003c\/li\u003e\n\u003cli\u003eCompact design with minimum change in the delay line\u003c\/li\u003e\n\u003cli\u003eEntrance and exit iris diaphragms for alignment\u003c\/li\u003e\n\u003cli\u003eVacuum-compatible, remotely controllable\u003c\/li\u003e\n\u003cli\u003eEasy to implement in existing setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplication Notes — Magnetic Circular Dichroism\u003c\/h3\u003e\n\u003cp\u003eAURORA is the perfect tool for attosecond magnetic circular dichroism (MCD) experiments. As demonstrated in Siegrist et al. \u003cem\u003eNature\u003c\/em\u003e 571 (2019), AURORA was used to provide high ellipticity and transmission at the Nickel M-edge (~66-68 eV), enabling element-specific tracking of coherent ultrafast spin dynamics in multilayer systems. The working range also covers M-edges of Fe (52.7 \/ 58.9 eV) and Co (59.9 eV) for further studies.\u003c\/p\u003e\n\u003ch3\u003eReferences\u003c\/h3\u003e\n\u003col\u003e\u003cli\u003eSiegrist F., Gessner J.A., Ossiander M. et al.
