Members of the CDHS neutrino experiment (WA1) celebrating the end of data taking

The CDHS neutrino experiment at CERN was a collaboration of CERN, Dortmund, Heidelberg and Saclay (later joined by Warsaw) led by Jack Steinberger. The experiment was designed to study deep inelastic neutrino interactions in iron. The detector had a mass of 1250 tons and combined the functions of a muon spectrometer and hadron calorimeter. It consisted of 19 magnetized iron modules, separated from each other by wire drift chambers. The experiment took data in the CERN neutrino beams from December 1976 until 1984.
