Charpak, Georges zhôrzh shärpäk´ [key], 1924–2010, French physicist, b. Dąbrowica, Poland (now Dubrovytsia, Ukraine), Ph.D Collège de France, 1954. Affiliated with CERN (1959–91), Charpak won the 1992 Nobel Prize in Physics for the invention of particle detectors, particularly the multiwire proportional tracking chamber, which uses tiny wires to measure the electrical impulses of particles produced in collision in particle accelerators. His devices greatly aided scientific experimentation in particle physics.
