Notes:
A triple-axis diffractometer has been constructed and optimized in our laboratory. It is used on an X-ray point source, using the principle which was pioneered by Bonse and Hart 25 years ago. A triple-reflection channel-cut Ge crystal is used as monochromator and the same as analyser. The width of the direct beam is about FWHM = 17′′ for Cu Kα radiation. Owing to the low background, the stability of the mechanics and the two triple Ge reflections, a signal-to-noise ratio of 107 has been achieved between the direct beam and the parasitic scattering without sample. These characteristics allow routine measurement of scattering to be performed for Bragg spacings up to 6000 Å for typical colloidal samples in semilinear collimation.
