A high-resolution small-angle X-ray scattering camera has been built, which has the following features. (i) The point collimation optics employed allows the scattering cross section of the sample to be directly measured without corrections for desmearing. (ii) A small-angle resolution better than 0.5 mrad is achieved with a camera length of 1.6 m. (iii) A high photon flux of 0.9 photons μs−1 is obtained on the sample with the rotating-anode X-ray generator operated at 40 kV–30 mA. (iv) Incident X-rays are monochromated by a bent quartz crystal, which makes the determination of the incident X-ray intensity simple and unambiguous. (v) By rotation of the position-sensitive proportional counter around the direct beam, anisotropic scattering patterns can be observed without adjusting the sample. Details of the design and performance are presented with some applications.

AbstractAn ultra-high vacuum chamber designed for in situ grazing incidence small angle x-ray scattering (GISAXS) surface analysis is described. Unique features of this equipment are the precision rotary feedthrough for angular alignment of the sample, the sample heating design, the Be window arrangement, and the compatibility of this chamber with both a rotating anode and a synchrotron beamline. This chamber was used as part of a GISAXS camera utilizing a 18 kW Rigaku rotating anode, pin-hole collimation, and a position sensitive detector. The resolution of this camera was 0.007 A-1 with a 1.4 mm wide beamstop and CuKα

When a one-dimensional position-sensitive proportional counter (PSPC) is employed in a small-angle X-ray scattering (SAXS) system, detector-related problems might be encountered, such as nonuniformity of the detector, resolution function defined by the geometry of the receiving slit etc., all of which could cause distortion to the measured intensity profile. A set of experiments has been performed to test the significance of some of these problems, and corrections have been worked out to circumvent them. To obtain an optimized condition between flux and resolution, a wedge-shaped receiving slit is recommended.
