The GMX N-type Coaxial HPGe Detector is a high-performance gamma spectroscopy detector engineered for applications requiring both ultra-low energy sensitivity and high-energy efficiency. What sets the GMX series apart is its ultra-thin ion-implanted entrance window (~0.3 µm), significantly thinner than conventional coaxial detectors. This enables detection of gamma and X-rays down to approximately 5 keV, making it ideal for low-energy spectroscopy applications. Built with N-type germanium, the detector offers enhanced resistance to fast neutron damage, ensuring stable long-term operation in high-radiation environments. The GMX detector uniquely combines excellent performance at both low and high energies, delivering reliable efficiency, superior peak shape, and high-resolution spectral data across a broad energy range. With advanced options such as SMART bias, low-background endcaps, and high-rate preamplifiers, the GMX series is an ideal solution for laboratories requiring precision, durability, and versatility in gamma spectroscopy.
