Rigaku Ultima IV




The Ultima IV represents the state-of-the-art in multipurpose X-ray diffraction (XRD) systems. Incorporating Rigaku's patented cross beam optics (CBO) technology for permanently mounted, permanently aligned and user-selectable parallel and focusing geometries, the Ultima IV X-ray diffractometer can perform many different measurements...fast. With a multipurpose diffractometer, performance is measured by not only how fast you perform an experiment but also how fast you can switch between different types of experiments. Individual experiments are optimized with accessories like the D/teX Ultra high-speed position sensitive detector system, but the speed between experiments is radically improved with the combination of the automated alignment and CBO.

The Ultima IV incorporates fully automatic alignment. When coupled with CBO and the in-plane arm, the automatic alignment capability makes the Ultima IV X-ray diffractometer the most flexible system available for multipurpose applications. This diffractometer can be set up for SAXS and Thin Film measurements.

The instrument is located in 1709 Gilman Hall. Enquiries should be directed to Dr. Arkady Ellern. Phone 515-294-7956 (office).  The instrument is primarily walk-on, but can be "Booked" for special projects.  Reservations require approval.
