HPGe Detectors

High purity germanium (HPGe) detectors are semiconductor detectors that offer the highest energy resolution available for gamma and X-ray spectroscopy. Cooled with liquid nitrogen, they can separate closely spaced gamma lines that scintillators cannot resolve, making them the reference choice when you need to identify and quantify many radionuclides in the same sample. They are used across nuclear energy, environmental monitoring, industry, research and medicine. In an Australian context, that includes laboratory analysis of soil, water and food samples, radiopharmaceutical quality control, mining and mineral processing, and university nuclear physics teaching. An HPGe detector is typically paired with a digital MCA such as the CAEN SyS Hexagon, which provides the detector bias and high resolution spectroscopy. Detector size, crystal geometry, shielding and cooling method all affect performance, so the right configuration depends on your samples and count rates.
