HPGeγAs an advanced nuclear radiation detection and analysis device, the energy spectrometer plays an important role in various fields such as scientific research, industry, and environmental protection due to its excellent performance and wide range of applications. This article will focus onCanberraTaking high-purity germanium measurement system as an example, explore its characteristics and applications.

Overview of Characteristics

CanberraThe high-purity germanium measurement system is a high-performance systemγThe energy spectrum measurement system integrates high-purity germanium detectors, refrigeration devices, digital multi-channel spectrometers, low background lead chambers, and advanced energy spectrum acquisition and analysis software. This system has the following significant features:

High energy resolution：CanberraThe system uses high-purity germanium crystals as the detector core, with extremely high energy resolution. for example, in1332.5keVEnergy point, with an energy resolution of up to1.65keVIt can accurately distinguish adjacent energy peaks and provide reliable basis for nuclide identification.

High degree of automation: The system is equipped with fully automated energy spectrum analysis software that supports interactive analysis, making it particularly suitable for non specialized personnel to use. Built in software3000The radiation information of multiple isotopes is closely integrated with the nuclide library and energy spectrum analysis software, making it easy for users to obtain analysis results.

Strong system stability: Electronic systems such as multi-channel and high-voltage modules use grade devices and have been specially designed for temperature stability. The system has excellent long-term stability, and even after continuous measurement for one month, the energy resolution can still be maintained below1.9KeV.

No need for standard source efficiency calibration: The system adopts passive efficiency calibration technology, which eliminates the need to produce and use standard sources, avoids representativeness issues between samples and standard sources, reduces management costs, and improves detection efficiency.
