Abstract

In order to improve the accuracy of the PIXE analysis with respect to the pile-up problem, a technique to analyze PIXE spectra suffering from pile-up has been developed. The idea is to use the well known relationship Na*Nb*t=N, where Na and Nb are the count rates in to primary peaks, t is the pile-up interval and N is the count rate in the resulting pile-up peak. In order to compensate the spectrum for the pile-up effects despite a varying count rate. The X-ray energy signal together with the current are collected in the list mode event-by-event, enabling a time-resolved analysis of the spectrum.
