New approach for preparation of high-purity sulfide-germanium glasses doped with praseodymium

Preparation and Characterization of Yb3+-Doped Metaphosphate Glasses for High Energy and High Power Laser Applications

Ytterbium-doped metaphosphate laser glasses were prepared by the melt-quenching technique and their optical, thermo-mechanical and laser properties were characterized. Linear and non-linear refractive indices, laserinduced damage threshold, microhardness number and thermal expansion co-efficient have been evaluated for 1.0 mol% Yb2O3-doped glass. Low non-linear refractive index, high laser-indu...

Digital Timing Algorithm for High Purity Germanium Detectors

The next generation of γ-ray detector arrays will be composed of large volume high purity germanium (HPGE) detectors that are electronically segmented. These detectors will be able to track γ-rays as they Compton scatter within the crystal and between adjacent crystals, eliminating the need for Compton suppression detectors and improving angular resolution. The new arrays will have much higher ...

The Best Choice of High Purity Germanium (HPGe) Detector

below and are based on some basic concepts about how the detection process works, how gamma rays penetrate materials, and the principles of gamma-ray spectroscopy. Unresolved choice issues can be reduced to a level where they have little or no impact on the resultant performance of the spectrometry system. This document explains how you can easily make a wise, well-informed choice. We assume yo...
