Pulse loss and counting statistics with a digital spectrometer

Research output › peer-review

Abstract

A commercially available digital γ-ray spectrometer is tested at high count rates using a germanium detector and appropriate pulse processing parameters. Correction for pulse loss due to dead time and pileup is done by extending the live time according to the Gedcke-Hale method. The accuracy of this count-loss correction technique is tested experimentally up to saturation count rates. Also the statistical uncertainty applicable to the total number of counts in arbitrary regions of interest in γ-ray spectra is studied experimentally, for measurements at fixed real time as well as at fixed live time. The results are similar to those found with traditional spectrometers using analog technology. (C) 2000 Elsevier Science Ltd.
