Particle detectors, as a technique, encompass the ensemble of methods and instrumentation used to register, localize, and characterize ionizing particles through their interactions with matter. These techniques exploit processes such as ionization, scintillation, Cherenkov radiation, and semiconductor charge collection to convert particle passage into measurable electrical or optical signals. Detector techniques include tracking (e.g., gaseous wire chambers, silicon strip and pixel detectors), calorimetry (sampling and homogeneous calorimeters for energy measurement), and time-of-flight methods for velocity determination, often integrated in complex, layered systems enabling precise reconstruction of particle trajectories, momenta, identities, and interaction vertices in nuclear, particle, and astroparticle physics experiments.
For nearly a century, scientists around the world have been searching for dark matter—an invisible substance believed to make up about 80% of the universe's mass and needed to explain a variety of physical phenomena. Numerous ...
