MAX IV Laboratory

Description

Simultaneous XAS (x-ray absorption) + XES (x-ray emission). XAS at 2.4 – 40 keV; XES at 2.3 – 25 keV with two independent braches (for two energy bands). Quick scanning: full EXAFS for 0.5 sec. Gas infrastructure for in-situ and in-operando catalysis. Several in-situ catalysis cells available. LHe cryostat with quick sample exchange. Simultaneous powder XRD. Reflective XAFS setup. Microfluidics setups.

Equipment and resources

Two 7-element fluorescence detectors. XES spectrometer with 3 crystal sets. LHe close-cycle cryostat. Gas handling and mixing system with a vaporizer and MassSpec. Several in-situ cells.
Digital data of absorption and emission spectra.

Services provided

User support during user beamtime. Measurements of post-in samples including data quality control (implemented later).

Management of the infrastructure

The beamline is headed by a beamline scientist, time for experiments is allocated through a peer review process by an external program advisory committee. The scientific scope of the beamline is defined in interaction with the management of MAX IV Laboratory and the Scientific Advisory Committee.
