Abstract

A log-spirally bent crystal Laue analyzer has been investigated and developed for highly sensitive in situ surface X-ray absorption fine structure (XAFS) measurement. Both calculations and experiments were conducted to obtain its intensity distributions on the different positions of the analyzer. A home-made log-spirally bent crystal Laue analyzer was made and evaluated. It was revealed that higher XAFS signals were obtained with the home-made analyzer than with the commercial one.
