Particle detectors are devices used in experimental physics to detect and measure subatomic particles such as electrons, protons, and neutrons. These detectors are used in a wide range of scientific disciplines, including high-energy physics, nuclear physics, and medical imaging. Particle detectors work by interacting with passing particles, producing a signal that can be detected and analyzed. There are several types of particle detectors, including scintillation detectors, semiconductor detectors, and calorimeters, each with its own strengths and limitations. Particle detectors play a crucial role in fundamental research, helping scientists study the structure of matter, explore the fundamental forces of nature, and uncover new particles and phenomena. They are also used in practical applications such as medical imaging, security screening, and environmental monitoring.
