Anti-Compton / Anti-Cosmic Ray Ultra-Low Background High-Purity Germanium (HPGe) Gamma-Ray Spectrometer — SIM-MAX HPGe1620 Series

The SIM-MAX HPGe1620 Series Anti-Compton/Anti-Cosmic Ray Ultra-Low Background High-Purity Germanium (HPGe) Gamma Spectrometer employs a newly developed, proprietary anti-coincidence detector. This system achieves extremely low background levels and high-performance suppression of Compton scattering, making it ideally suited for measuring the activity of low-energy radionuclides in both ultra-low-level and high-radioactivity environments. Furthermore, the system allows for the selection of the optimal measurement mode tailored to the specific characteristics of the sample being analyzed.

Key Features

– The anti-coincidence detector utilizes a high-density NaI crystal that is resistant to deliquescence, facilitating the optimization of the instrument’s peak-to-Compton ratio and integrated background performance.
– Incorporating mature coincidence/anti-coincidence logic gating circuits and a sound mechanical design, the system not only ensures enhanced operational stability but also enables a single unit to perform multiple measurement functions (anti-Compton, anti-cosmic ray, or combined anti-Compton/anti-cosmic ray measurements).
– Features a high-resolution dual-channel multichannel analyzer that provides a clear, intuitive display of spectral data both before and after anti-coincidence processing.
– Integrates a low-background lead chamber design, utilizing composite shielding materials within its interior.
– Includes a comprehensive data processing system that seamlessly integrates data acquisition and analysis capabilities.
– Provides access to the IAEA nuclide library, comprising data on nearly 1,700 different nuclides.
– Supports the customization of various measurement modes: high-efficiency measurement, γ-γ coincidence, and γ-β coincidence measurements.
– Offers optional cooling configurations: liquid nitrogen recirculation/recondensation (hybrid liquid nitrogen and electric cooling) or standard liquid nitrogen cooling.
