Experimental Station

The SUT-NANOTEC-SLRI XAS Experimental Station is designed to accommodate a wide variety of samples, focusing on determining local atomic structures and oxidation states.

Standard Setup

  • Sample Stage: A versatile mounting stage adaptable for standard holders or specialized in-situ chambers.
  • Transmission Mode: Ionization chambers before and after the sample measure X-ray flux absorption. This mode is suited to concentrated samples.
  • Fluorescence Mode: A four-element Silicon Drift Detector is placed perpendicular to the beam path for dilute samples or thin films.
