Abstract:
The ID11-L HESEB Soft X-ray beamline and end station significantly enhance soft X-ray research capabilities. Operating in an energy range of 90–1800 eV, extendable to 70–2000 eV, the beamline achieves high performance with an energy resolution of E/ΔE > 8000 and a photon flux of 1010 to 3.4 × 1012 photons/s. Its 500 × 250 μm< beam spot size allows for precise measurements, including studies on magnetic materials using variable circular polarization. This paper presents the end station's design, including the receptacle, magnetic sample holder, and ambient pressure capabilities, along with experimental results that demonstrate the beamline's potential for diverse scientific applications.
