X-RAY ATTENUATING MEMBER, X-RAY ATTENUATING METHOD, XAFS (X-RAY ABSORPTION FINE STRUCTURE) EXPERIMENTAL APPARATUS AND XAFS MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To set X-ray intensity within a detection limit (a proportional region) of an X-ray detector without a replacement of the X-ray detector and an output adjustment of an X-ray source.

SOLUTION: The X ray is made to enter at a predetermined location an X-ray attenuating member 10 continuously changing its own thickness in the longitudinal direction L. The X-ray intensity is attenuated at an attenuation rate corresponding to the thickness at the incident location of the X ray in the X-ray attenuating member 10.
