We introduce a coherent diffractive imaging technique that utilizes multiple exposures with modifications to the phase profile of the transmitted wave front to compensate for the missing phase information. This is a single spot technique sensitive to both the transmission and phase shift through the sample. Along with the details of the method, we present results from the first proof of principle experiment. The experiment was performed with 6.0 keV x rays, in which an estimated spatial resolution of 200 nm was achieved.

    • "Detectors are key components in many applications at x-ray synchrotrons and free-electron lasers [1] [2] [3] [4] [5] [6]. The unprecedented data quality and high dynamic range of detectors has driven advancements in many fields of research, especially in protein crystallography [7] [8], scanning small-angle x-ray scattering [9], coherent diffraction imaging [10] [11] and x-ray photon correlation spectroscopy [12] [13] "

    ABSTRACT: Eiger is a single-photon counting x-ray pixel detector being developed at the Paul Scherrer Institut (PSI) for applications at synchrotron light sources. It follows the widely utilized and successful Pilatus detector. The main features of Eiger are a pixel size of 75 × 75 μm2, high frame rate capability of 22 kHz and negligible dead time between frames of 4 μs. This article contains a detailed description of Eiger detector systems, from the 500 kpixel single-module detector to large-area multi-modules systems. The calibration and performance of the first 500 kpixel system that is in routine user operation are also presented. Furthermore, a method of calibrating the energy of single-photon counting detectors along the detector gain axis is introduced. This approach has the advantage that the detector settings can be optimized at all energies for count rate capabilities. Rate capabilities of the system are reported for energies between 6 and 16 keV.

    ABSTRACT: EIGER is the next generation of single photon counting pixel detector for synchrotron radiation designed by the PSI-SLS detector group. It features a pixel size of 75 × 75μm2 and frame rates up to 23 kHz. The chip contains 256 × 256 pixels, has a total size of 19.3 × 20 mm2 and provides 4, 8 and 12 bit counting modes. This dynamic range is extendable to 32 bits with continuous read/write and summation of frames on the fly in firmware. Along with X-ray absorption images, the characterization and performance of the chip is presented. The energy calibration, noise, minimum energy threshold and rate capability measured with a single chip test system in a X-ray tube and at the SLS-PSI synchrotron are shown. Trimming studies and irradiation effects are discussed as well. To conclude, the status of the production of larger detector systems consisting of 2 × 4 chip modules and multi modules detector systems (9 Mpixels; 3 × 6 modules) is outlined.

    ABSTRACT: The Gastroenterology Core Curriculum published in this issue of Gastroenterology is the product of a 2-year, in-depth analysis of the knowledge and skills desired at the completion of fellowship training in gastroenterology and the specific training process to achieve these goals. This curriculum is a result of the cooperative effort of the American Association for the Study of Liver Diseases, the American College of Gastroenterology, the American Gastroenterological Association, and the American Society for Gastrointestinal Endoscopy working together under the auspices of the Gastroenterology Leadership Council (GLC). The development of this curriculum was made possible by the formation of the GLC Training Committee, which is composed of representatives from the training committees of all four societies, in an effort to reach consensus on training issues. Dr. Lawrence Friedman is to be congratulated for his effective leadership as Chair of the GLC Training Committee, which also served as the Oversight Committee for the curriculum project, and for his skillful shepherding of this joint-society effort through the broad consensus process needed to reach a final product. The Gastroenterology Core Curriculum is a prime example of what can be achieved by the cooperative efforts of the four major gastroenterology/hepatology societies.GASTROENTEROLOGY 1996;110:1266
