Abstract
A method of processing signals relating to a plurality of X-rays received in an X-ray spectrometry system that includes a pulse processor having a main channel and zero or more fast channels includes steps of receiving a main channel dead time signal and zero or more fast channel dead time signals generated by the pulse processor, detecting an occurrence of a plurality of piled-up X-rays in an X-ray pile-up sequence using one or more of the main channel dead time signal and the zero or more fast channel dead time signals, counting the X-rays in said pile-up sequence, and if one or more fast channels are present, classifying an energy band of each of the piled-up X-rays using one or more of the main channel dead time signal and the one or more fast channel dead time signals.
