cryogenic detector

A cryogenic detector is a device used by scientists to observe extremely faint signals, such as particles or radiation, by cooling materials to very low temperatures close to absolute zero. At these temperatures, the detector’s ability to sense tiny energy changes improves significantly, allowing it to detect events that would otherwise be invisible. This technology is essential in fields like astrophysics and particle physics, helping scientists explore phenomena like cosmic rays or dark matter. By reducing thermal noise, cryogenic detectors achieve high sensitivity, making it possible to study the universe’s most subtle signals.
