• Ring imaging Čerenkov detector — A Ring Imaging Čerenkov detector (RICH detector) is a particle detector that can determine the velocity, v , of a charged fundamental particle. This is done by an indirect measurement of the Čerenkov angle, heta c , i.e. the angle between the… …   Wikipedia

• CLEO (particle detector) — CLEO was a general purpose particle detector at the Cornell Electron Storage Ring (CESR), and the name of the collaboration of physicists who operated the detector. The name CLEO is not an acronym; it is short for Cleopatra and was chosen to go… …   Wikipedia

• Cherenkov detector — A Cherenkov (Čerenkov) detector is a particle detector using the mass dependent threshold energy of Cherenkov radiation. This allows a discrimination between a lighter particle (which does radiate) and a heavier particle (which does not radiate) …   Wikipedia

• Smoke detector — A smoke detector is a device that detects smoke, typically as an indicator of fire. Commercial, industrial, and mass residential devices issue a signal to a fire alarm system, while household detectors, known as smoke alarms, generally issue a… …   Wikipedia
