Determination of and compensating for count losses for the correctness of analyses in spectrometric analysis of qualitative and quantitative use of semiconductor detectors are of importance. These counting losses in spectrometry are due to the pulse pile-up, paralyzable and non-paralyzable system dead time or dual and triple combination of these three mechanisms. In this work, a new method is suggested for compensate for counting losses resulting from abovementioned three factors. For this purpose, a source code was developed. A number of experimental studies were performed to test the proposed method. As a result, it was seen to provide an effective correction of proposed method at low-and middle-grade counting rates.

Reducing count losses and pile-up pulse effects in quantitative and qualitative analysis is necessary for accuracy of analysis. Therefore, the proper peaking time for particular detector systems is important. The characteristic X-rays emitted from pure some elements were detected by using an Ultra-LEGe detector connecting a Tennelec TC 244 spectroscopy amplifier at different peaking time modes. Overall pulse widths were determined by an HM 203-7 oscilloscope connecting amplifier. The proper peaking time for Ultra-LEGe is determined as 3.84 mu s. (C) 2011 Elsevier Ltd. All rights reserved.
