The experimental hutches have a heavy 20cm thick granite alignment table. Mounted first on the table are a double pair of highly accurate beam defining slits, followed by a fast and accurate piezo shutter good for millisecond exposures. The sample is mounted on a precise airbearing goniometer for accurate X-ray diffraction measurements from ever smaller crystals. A high resolution video-microscope is mounted co-axial with the X-ray beam axis that allows the sample position to be viewed without parallax error. The sample may be manipulated and the crystal centered using a simple three-click procedure on a nearby PC or from the beamline control PC. MX beamlines are equipped with CCD detectors for accurate and fast (as quick as ~2s per frame on MAD stations with ADSC 315s) data collections. An Oxford Cryostream (700 series) with an automatically filled dewar is available for cryo-cooling (effectively necessary for all experiments on the beamline). A 50 crystal sample changer will be available on all beamlines this Summer (2005).
