Switzerland Cern, 1972 (b/w photo)

Gargamelle at the nuclear research institute CERN, pictured on April 22, 1971, in Meyrin near Geneva, Switzerland. The heavyweight water tank (900 tons) “Gargamelle” played an important role in the discovery and research of so-called neutrinos (elementary particles), which provides information on distant galaxies, supernovas and our sun. CERN is an international organization for high-energy and nuclear physics, where matter is researched by accelerating and bringing to collision elementary particles such as electrons and proton. Founded in 1954, the CERN is the largest research institute of its kind.
