The x-ray diffraction and scattering beamline and results of the performance tests at NSRL

Extending the spectral range to hard X-ray, a superconducting wiggler was constructed and installed at the 0.8 Gev storage ring of National Synchrotron Radiation Laboratory to produce a radiation with the critical energy of 2.55 keV. The wiggler radiation fan of horizontal 35 mrad has been split into three branches to be equipped with three beamlines for studies on extended X-ray absorption fine structure (XAFS), X-ray diffraction and scattering (XRDS) and X-ray deep lithography (LIGA), respectively. This paper reports the design, the results of performance tests of the XRDS beamline and the preliminary data collection on a protein crystal of acutohaemolysin at the experiment station.
