General beamline description and specificationsThe PHOENIX (Photons for the Exploration of Nature by Imaging and XAFS) beamline is dedicated to X-ray absorption spectroscopy performed in the tender X-ray energy range, with high photon flux produced by an elliptical APPLE II undulator. Two different flexible endstations provide the users the state-of-the-art equipment to conduct X-ray micro-spectroscopic measurements (µ-XAS and µ-XRF) on samples kept in different environments.
Examples of experiments which could be performed at the PHOENIX beamline :
- High quality EXAFS for low-Z elements, see for example Al K-edge in Fulton et al., JACS 136 (2014),
- In situ XAS studies on functioning ion batteries, at the S K-edge in Gorlin et al., J. Electrochem. Soc. 162 (2015),
- Micro-spectroscopy on cultural heritage using micro-focused beam, e.g. Cato el al., Microchem. J. 126 (2016), and Meyer et al., Scanning (2017),
- XAS study of UV radiation damages in biological samples, e.g. J. Czapla-Masztafiak et al., Biophys. J. 110 (2016),
- Various liquid cells and liquid jets available for in-situ studies of chemical reactions (in collaboration).
The Phoenix Group is part of the Laboratory for Synchrotron Radiation and Femtochemistry (LSF).
