The IMB X-Ray Crystallography Facility features four separate instrument set-ups for x-ray diffraction data acquisition. The Rigaku Osmic Xentronics Area Detector (ROXAD) set-up consists of a rotating anode generator, special SAXS multi-layer optics and a multiwire area detector. The x-ray source is a 12 kW Rigaku RU-H2R rotating anode generator (running at 44 kv and 94 mA) with a copper anode and a 0.3 x 3.0 mm2 x-ray filament (cathode). An Osmic SAXS confocal mirror system purged in helium gas images the x-ray filament at 6° angle creating a foreshortned (reduced 1/10 on one dimension) 0.3 x 0.3 mm2 point image that is collimated and focussed at the detector. The multiwire area detector has an active area of 100 mm diameter with a 0.195 x 0.195 mm resolution in each directions. Note: As of November 2008, the area-detector is no longer functional and needs to be replaced.
