germanium detector

A germanium detector is a type of solid-state detector that uses a semiconductor material, most commonly germanium, to detect ionizing radiation. When radiation interacts with the germanium crystal, it creates electron-hole pairs. An electric field within the detector causes these charges to move, generating a measurable electrical signal. This signal can be analyzed to determine the energy, number, or identity of the incident radiation. Germanium detectors are known for their excellent energy resolution, making them valuable for applications like gamma-ray spectroscopy. Due to thermal vibrations, these detectors are typically operated at low temperatures, often cooled to liquid nitrogen temperatures, to minimize unwanted signals and improve accuracy.12
