Double-Drift Thin-Window Planar Ge(Li) Detectors

An improved method for fabricating a thin-window planar detector was developed at Lawrence Radiation Laboratory, Livermore. This detector is designed to analyze spectra of low-energy as well as high-energy gamma and x rays. The detector has a planar configuration with a relatively large gold surface barrier entry window. The main advantage of this detector is its faster drifting time coupled with minimum waste of material. This method of fabrication has significant advantages over earlier techniques.
