FLUXS–FLASH Liquid-phase Ultrafast X-ray Spectroscopy
The FLUXS end-station is built for conducting versatile liquid-phase spectroscopic instrument for advanced solution-phase spectroscopy in the soft X-ray regime. By constructing a flexible system, this end station is able to conduct (i) X-ray absorption spectroscopy (XAS) in transmission mode, (ii) pink-beam post-sample dispersive X-ray absorption spectroscopy (dXAS), potentially in combination with beam splitting techniques for referenced detection, (iii) partial fluorescence yield (PFY) absorption spectroscopy for low-concentration samples, and (iv) resonant inelastic X-ray scattering/resonant X-ray emission spectroscopy (RIXS/RXES). The spectrometer aims for an intermediate energy resolution (E/ΔE ≤ 1000) for liquid-phase science. The compact and flexible design allows for switching between transmission and scattering schemes.
