Leakage current in high-purity germanium detectors with amorphous semiconductor contacts

Germanium Orthogonal Strip Detectors with Amorphous-Semiconductor Contacts

Germanium orthogonal strip detectors have been produced using amorphous-semiconductor contacts. The amorphoussemiconductor contact fabrication process is relatively simple, and it is capable of producing fine-pitched electrode structures. The bipolar blocking behavior of the amorphoussemiconductor contact permits its use on both sides of a detector, replacing conventional B ion implanted and Li...

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 ...

Measurement of the Potassium Content of Different Food Samples with High Purity Germanium Detectors

Measurements of the potassium content of samples of food, performed with High Purity Germanium detectors, are presented in this paper. The potassium content was measured by identifying the 1460 keV photons produced in the decay of the isotope 40K. Samples were selected, for which a high potassium content was expected. The measurements confirmed the expectations qualitatively, but not always qua...

Performance Characteristics of a Third-generation Spectroscopic Vehicle Portal Monitor based on High Purity Germanium Detectors

The general need for improved detection performance and reduced decision time for portal monitors, freight container scanners, and mobile search systems is being achieved with systems utilizing High-Purity Germanium (HPGe) detectors. Highly specialized software analyzes the spectroscopic data to produce accurate results in live time. To meet the need, a new generation monitor has been developed...
