Cherenkov radiation glowing in the core of the Advanced Test Reactor at Idaho National Laboratory. Cherenkov radiation (/ tʃ ə ˈ r ɛ ŋ k ɒ f / [1]) is electromagnetic radiation emitted when a charged particle (such as an electron) passes through a dielectric medium (such as distilled water) at a speed greater than the phase velocity (speed of propagation of a wavefront in a medium) of ...
The Frank–Tamm formula yields the amount of Cherenkov radiation emitted on a given frequency as a charged particle moves through a medium at superluminal velocity. It is named for Russian physicists Ilya Frank and Igor Tamm who developed the theory of the Cherenkov effect in 1937, for which they were awarded a Nobel Prize in Physics in 1958.
Cherenkov radiation is not only present in the range of visible light or UV light but also in any frequency range where the emission condition can be met i.e. in the radiofrequency range. Different levels of information can be used. Binary information can be based on the absence or presence of detected Cherenkov radiation.
A polar plot of the Cherenkov angles of photons associated with a 22 GeV/c particle in a radiator with =1.0005 is shown in Fig.2; both pion and kaon are illustrated; protons are below Cherenkov threshold, / >, producing no radiation in this case (which would also be a very clear signal of particle type = proton, since fluctuations in the number ...
The Track Imaging Cherenkov Experiment (TrICE) is a ground-based cosmic ray telescope located at Argonne National Laboratory near Chicago, IL.The telescope, which contains a Fresnel lens, eight spherical mirrors, and a camera with 16 multianode photomultiplier tubes, uses the atmospheric Cherenkov imaging technique to detect Cherenkov radiation produced when cosmic rays interact with particles ...
The emission of blue light is often attributed to Cherenkov radiation. [8] [verification needed] Cherenkov radiation is produced by charged particles which are traveling through a dielectric substance at a speed greater than the speed of light in that medium. Despite the production of similarity-colored light and an association with high-energy ...
NEVOD (Russian: НЕВОД, НЕйтринный ВОдный Детектор, Neutrino Water Detector; nevod means "dragnet" in Russian) is a neutrino detector and cosmic ray experiment that attempts to detect Cherenkov radiation arising from interactions between water and charged particles (mostly muons). It represents the first attempt to ...
MAGIC, a Cherenkov telescope in operation on the Canary island of La Palma.On foggy nights, the lasers that are used to focus the mirrors can be seen. IACT (imaging atmospheric [or air] Cherenkov telescope [1] [or technique] [2] [3]) is a device or method to detect very-high-energy gamma ray photons in the photon energy range of 50 GeV to 50 TeV.
