摘要：

To expand the detection efficiency Silicon Drift Detectors (SDDs) with various customized radiation entrance windows optimized detector areas and geometries have been developed Optimum values for energy resolution peak to background ratio (P/B) and high count rate capability support the development Detailed results on sensors optimized for light element detection down to Boron or even lower will be reported New developments for detecting medium and high X-ray energies by increasing the effective detector thickness will be presented Gamma-ray detectors consisting of a SOD coupled to scintillators like Csl(TI) and LaBr3(Ce) have been examined Results of the energy resolution for the Cs-137 662 key line and the light yield (LY) of such detector systems will be reported (C) 2010 Elsevier B V All rights reserved
