Neutrino scintillation detector, 1953. Scintillation counter detector (cylindrical, right) used by US physicist Frederick Reines (1918-1998) and US physicist Clyde Cowan (1919-1974) in their first neutrino experiment at the Hanford Site, Washington, USA, in 1953. The experiment was later continued at the Savannah River Plant in South Carolina, USA. Known as the Cowan-Reines neutrino experiment, by 1956 enough data had been gathered to confirm the existence of the neutrino (the particle detected was the electron antineutrino). Reines was awarded the 1995 Nobel Prize in Physics for this work. Photographed in 1953.
