Editing Ring-imaging Cherenkov detector (section)

The '''ring-imaging Cherenkov''', or '''RICH''', detector is a device for identifying the type of an [[electrically charged]] [[subatomic particle]] of known [[momentum]], that traverses a [[transparency and translucency|transparent]] [[refractive]] medium, by measurement of the presence and characteristics of the [[Cherenkov radiation]] emitted during that traversal. RICH detectors were first developed in the 1980s and are used in high energy [[elementary particle]]-, [[Nuclear physics|nuclear]]- and [[astro-physics]] experiments.
