Optics hutch 2

The equipment in OH 2 is energy-dispersive XAFS system, experimental system for biomedical application experiments, diffractometer and X-ray tomographic stage for long objects.
Samples can be cooled down to 3.8 K by He cryostat and also heated up to 1770 K by infrared heater.

• Energy-dispersive XAFS system
  • The main equipment of the DXAFS system consists of a polychromator with a bent silicon crystal, a higher-harmonic-rejecting mirror, and a CCD coupled with a scintillating screen and a lens system.
