Extract

The use of high-intensity, 8Kw, x-ray sources (Rigaku rotating-anode generator and wide - angle goniometer for this study) provides both opportunities and challenges. With high - intensity x-ray sources, detection limits can be lowered significantly while still offering count times of practical duration. On the other hand, the availability of high intensity x-ray sources puts greater demands on information extraction procedures and on the mechanical preciseness of sample containment and support. In particular we addressed the use of a cylindrical aluminum sample cell with a 0.010’’ polycrystalline (cold rolled) beryllium window electron –beam welded to an aluminum frame. See Figure 1. This cell permitted analysis of various air-sensitive specimens. The sample was pressed against the back of the beryllium window by a spring-loaded backing plate.
