SCXRD: The single crystal X-ray diffractometer

To complement the single crystal neutron instruments HEIDI and BIODIFF, an x-ray twin has been installed. The instrument comprises two microfocus X-ray sources, one with Molybdenum and one with Copper K radiation. These two sources make the instrument suitable for both small molecule and protein crystallography.
The sample area can be as large as a sphere with a radius of 4 cm. This makes it possible to accommodate high pressure cells or glass capillaries for room temperature operation. An Oxford Cryosystems Cryostream is available for low temperature operation down to 80 K.
An optical stereo microscope can be used for crystal mounting of small crystals. It is equipped with a camera which can record images with a known scale bar. This can be used to assess the crystal volume and morphology. Crossed polarizers can be used in transmission mode in order to see the birefringence of transparent crystals. This often helps to identify crystals of good scattering quality.
