Powder Diffractometer for Synchrotron Radiation with Multiple-Detector System.

Multiple-detector System for Powder Diffraction Using Synchrotron Radiation

A multiple-detector system for powder diffraction using synchrotron radiation was built and has been operated at the Photon Factory in Tsukuba since May, 1995. The optics design is based on a flat-specimen-reflection geometry using parallel-beam, and the intensity data are collected by using asymmetric 2@stepscanning at a fixed incident angle. The multiple-detector system makes it possible to c...

A two-circle powder diffractometer for synchrotron radiation on Station 2.3 at the SRS

Abinitio structure determination using dispersive differences from multiple-wavelength synchrotron-radiation powder diffraction data.

The purpose of this paper and a test case study is to assess a method of ab initio structure solution from powder diffraction data using f' difference techniques. A theoretical foundation for the approach used is first provided. Then, with a test case (nickel sulfate hexahydrate), it is shown that both the position of the anomalous scatterer (Ni) can be determined and the structure can be devel...

Synchrotron Radiation Monitoring System at Bepc

The synchrotron radiation by the relativistic particles is a useful and important diagnostic tool to obtain various beam parameters. The visible light of the synchrotron radiation emitted in a bending magnet of the BEPC storage ring is reflected through the window by a watercooled mirror in the vacuum chamber and then directed by a remote controlled mirror onto the optical bench supporting the ...
