Abstract

The spectral response of high-purity Ge and lithium-drifted Si (Si(Li)) surface barrier detectors of similar geometry has been measured over a range of X-ray energies under identical experimental conditions. Detector characteristics such as spectral background, escape peak intensity, entrance window absorption, and energy resolution are presented and compared. The authors attempt to consolidate the information on these characteristics by making comparisons under equivalent experimental conditions for the two types of detectors. A primary goal of the study is a comparison of the two types of detectors for use in X-ray fluorescence applications.<>
