The application of hard X-ray synchrotron radiation to materials has made it possible to obtain information hitherto impossible or impractical to obtain. Because the applications of synchrotron radiation are vast, this review concentrates on hard x-r

An experiment was performed on beamline BL 3 at the European Synchrotron Radiation Facility to test the diffraction performance of a novel internally liquid‐nitrogen‐cooled, thin silicon crystal monochromator exposed to high heat loads. The beam

Complementary neutron diffraction and anomalous x-ray diffraction techniques are used to probe the nature and origin of local and intermediate-range order in cesium germanate glass. Both neutron and differential x-ray structure factors reveal peaks a

We have developed a new design for a cryogenically cooled monochromator employing a thin‐crystal strategy which is capable of handling the central‐cone power of the advanced photon source’s undulator A at machine currents up to 300 mA. The key

In this article, a new technique, continuous energy diffraction spectroscopy (CEDS) is described, for diffraction experiments using a synchrotron energy dispersive polychromatic beamline. This type of beamline uses a curved crystal monochromator (pol

In this article we describe a new type of powder diffractometer that gives a significant improvement in count rate over existing methods. The key to the new technique is the use of a flat, diffracted beam monochromator in combination with a position

In general, a variable repetition rate of the x‐ray bunches is needed to explore time domain problems using x‐rays. In some instances, the results of several hundreds or thousands of x‐ray pulses must be averaged requiring the sample to be in t
