X-ray Diffraction Laboratory

Microstar - X8/Proteum Diffractometer

Microstar

   

This instrument uses a FR591 rotating anode generator with a mirror focusing optics giving a high brilliance X-ray flux enabling the analysis of very small and weakly diffracting single-crystals

The detector is a CCD camera for fast acquisition of the diffraction frames. A cryogenic system using liquid nitrogen is used to freeze the crystal and limit the radiation damage.

The diffractometer includes a robot for automatic mounting of frozen crystals stored in a deward filled with liquid nitrogen. It can be used for fast screening of crystal quality, including protein crystals.

The motorized goniometer head (in red on the picture) is able to center automatically the crystals.
