Transmission NEXAFS

nm liquid film Absorption

End station for time-resolved and steady-state soft x-ray absorption spectroscopy (XAS/NEXAFS/XANES/EXAFS) in transmission on liquid samples. The liquid is held between two SiN membranes in He (several 10 mbar) and forms a thin film. The film thickness can be varied between 50 nm and several µm. For details see: S. Schreck, G. Gavrila, C. Weniger, Ph. Wernet, "A sample holder for soft x-ray absorption spectroscopy of liquids in transmission mode", Rev. Sci. Instrum. 82, 103101 (2011).
