15 صفحه اولImproving Germanium Detector Resolution and Reliability
High purity germanium (HPGe) detectors used in radionuclide assay systems such as Radionuclide Aerosol Sampler/Analyzer (RASA) systems must operate unattended for long periods of time. Currently, the performance and reliability of commercially available large (~100%) HPGe detectors are acceptable for the majority of laboratory applications. However, for remote systems designed for nuclear deton...
متن کاملCharacteristics of an Integrated Germanium Detector Based
An integrated gamma ray spectrometer, incorporating a germanium detector with integral mechanical cooling, digital signal processing electronics, MCA, and communications has been developed. It is intended as a modular subsystem for wide application, including use in stationary or mobile systems for the detection of radioactive materials. The requirements for this application are good low and me...
متن کاملLarge Cryogenic Germanium Detector: Final Report
Cryogenic Germanium detectors are widely used in high energy physics and astrophysics – for example in direct dark matter searches (such as the Cryogenic Dark Matter Search experiment), or in neutrino-less double-beta decay experiments (such as MAJORANA). Potential future applications include X-ray observations and measurements of coherent neutrino scattering. In all of these fields, increasing...
