Dectris Ltd Neuenhoferstrasse 107 5400 Baden Switzerland Advances in instrumentation for the X-ray analysis (sponsored lecture) More than 100 years have passed since the interpretation of the first X-ray experiments resulted in crystal structures. Many structure determination methods have been devised since, mostly owing to the development of computer power. The experimental setup, however, remained deceivingly simple and unchanged throughout the century of crystallography. In its simplest form, the setup contains an X-ray source, a sample holder and a detector. Perhaps the most remarkable breakthrough in the instrumentation was invention of the synchrotron radiation. Owing to the highly brilliant, collimated and polarized beam, as well as tunable X-ray energy, synchrotron facilities enabled development of both research and methodology. Nowadays, brilliance of the third (and fourth) generation synchrotrons and the requirements of the material research community have exceeded the capabilities of traditional X-ray detectors. Therefore, the second big achievement in the instrumentation development was the development of single-photon-counting detectors. This new technology resulted in large (scalable) detectors whith the noise-free data, excellent statistics, and impressively reduced experimental time. These features opened up new possibilities in time-resolved measurements, protein crystallography and high resolution X-ray powder diffraction. This talk will concentrate on the single-photon-counting detectors, developed at Paul Scherrer Institute and commercialized through Dectris. In particular, on examples of PILATUS and MYTHEN, (i) requirements (ii) technology (iii) features and (iv) application of single-photon-counting detectors will be presented. Transition of these detectors to the laboratory diffractometers will be discussed. |
