Cherenkov detectors

Cherenkov detectors are devices that identify high-speed charged particles, like electrons, moving through a medium such as water or glass. When these particles travel faster than the speed of light in that medium, they emit a faint blue light known as Cherenkov radiation. This phenomenon occurs because the particle disrupts the electromagnetic field around it, leading to the emission of light. Cherenkov detectors are used in fields like nuclear physics and astrophysics to study particles from cosmic rays or to monitor radioactive materials, providing valuable information about their properties and behavior.
