XAS is developing, but, because it suffers from the fact that the “standard” Mg/Al dual anode X-ray gun usually limits the generation of intense Auger peaks to about half of the elements, this is a relatively slow development. It is necessary to obtain the optimum sharpest Auger peaks for high resolution XAS and for the precise determination of Auger Parameters. Therefore, a suitable unmonochromatic X-ray source should be selected for different elements or different transitions of an element. The Quadranode X-ray gun with the ability to emit three ranges (lower, medium and higher) of energy of X-ray photons is an appropriate candidate for modern XAS and XPS applications.
