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.
Protons and neutrons—the building blocks of matter—belong to a huge class of particles called hadrons. Hadrons are composite particles made of quarks that are bound together by the strong force. They are classified into two ...

Dark matter is an elusive form of matter that almost never emits, absorbs or reflects light, while only weakly interacting with regular matter. These properties make it very difficult to detect using conventional experimental ...
Artificial intelligence and machine learning are shaping major design and research decisions for the planned Electron-Ion Collider (EIC), a next-generation nuclear physics research facility that will collide electrons with ...

Theories of quantum mechanics predict that some particles can exist in superpositions, which essentially means that they can be in more than one state at once. When a particle's state is measured, however, this superposition ...
Proton beams are not only used in sophisticated nuclear physics experiments. Today, they are becoming increasingly popular in radiotherapy, where they are an irreplaceable tool for destroying cancer cells. Doctors and physicists ...
