摘要：

A new small-angle X-ray scattering instrument has been set up on the D2AM-ESRF beamline, This modular instrument, which has the capacity to handle different sample environments (variable temperature and pressure), is designed for easy wavelength changes, i.e. for anomalous-scattering studies. This paper describes its design and discusses in some detail its positioning and alignment with respect to the focusing optics. The mirrors were found to be a major; source of diffuse scattering, which was eliminated by rearrangement of the slit positions and refocusing of the optics. The present configuration yields a high flux (10(10) photons s(-1)) and allows measurements down to q = 0.005 Angstrom(-1).
