Particle detection is the field of physics that focuses on detecting and measuring subatomic particles, such as electrons, protons, neutrons, and photons. These particles are typically detected using various types of detectors, such as Geiger counters, scintillation detectors, and solid-state detectors. Particle detection is an essential component of many areas of physics research, including high-energy particle physics, nuclear physics, and astrophysics. By detecting and analyzing the behavior of these particles, scientists can gain insight into the fundamental properties of matter and the processes that govern the universe. Particle detection plays a crucial role in experiments conducted at particle accelerators, such as the Large Hadron Collider, as well as in the study of cosmic rays and neutrinos. It also has important applications in medical imaging, environmental monitoring, and homeland security.
