Abstract
An EXAFS (extended X-ray absorption fine structure) spectrometer incorporating a rotating anode X-ray source and standard optics with flat crystal is decreibed. By using a solid state detector to prevent harmonics and fast detection electronics to achieve a high count rate, we found that the conventional spectrometer can supply EXAFS spectra accurate enough for practical analysis. The systematic errors involved in EXAFS measurement are discussed in relation to the improvements designed into the present system.
