Cerenkov Counter

notes: label: Description
content: Cherenkov radiation is 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) of light in that medium. Pavel Čerenkov (1904-1990) was a Russian physicist who, together with compatriots Ilya Frank and Igor Tamm, received a Nobel Prize for Physics for their discovery and explanation of this type of radiation.
label: Description
content: The first particle velocity measurement by means of Čerenkov radiation was in the 1955 discovery of anti-protons by Owen Chamberlain, Emilio Segrè, Clyde Wiegand, and Thomas Ypsilantis at Berkeley’s 6 BeV proton synchrotron. This Čerenkov counter was used in that work.
