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.
In a collaboration showing the power of innovation and teamwork, physicists and engineers at the Department of Energy's Oak Ridge National Laboratory developed a mobile muon detector that promises to enhance monitoring for ...

A recent Physical Review Letters publication presents a thorough analysis of MicroBooNE detector data, investigating the anomalous surplus of neutrino-like events detected by the preceding MiniBooNE experiment.
Neutrinos are one of the most enigmatic particles in the standard model. The main reason is that they're so hard to detect. Despite the fact that 400 trillion of them created in the sun are passing through a person's body ...
