Gamma spectrometer and radiometer based on high purity germanium
The spectrometer QUADRO-HPGe is intended for studying the energy distribution of gamma rays and measuring the activity (specific activity) of gamma-emitting radionuclides in environmental samples, process medium, industrial materials, food products and other samples. It also used in a radiological monitoring of environmental objects in analytical laboratories and in the nuclear industry.
The operation principle of spectrometers is based on the registration of gamma-quanta emitted by radionuclides contained in the samples by an appropriate type of detector, which outputs an electrical impulse with amplitude, which is proportional to the energy of the detected gamma-quantum.
As a semiconductor detector in QUADRO-HPGE applied serially produced high-purity germanium detectors. The cooling system (dewar with LN2) is used to cool the detector. The work of spectrometer provides by spectrometric device, which contains a low-voltage power supply, generator high voltage and analyser.
