‎Rare stenciled report on the major international physics conference held in Copenhagen, 1952, sponsored by the Council of Representatives of European States ""for planning an international laboratory and organizing other forms of co-operation in nuclear research"" (From the introduction in the present report by Niels Bohr). This laid much of the technical foundation for the CERN-acceleration built two years later. ""[…] an international nuclear physics conference was held in Copenhagen"" on that occasion the type of accelerator to be built as the main goal of the new European organization was amply discussed. A report on the conclusions reached by the participants was presented by Heisenberg to the Council which held its Second Meeting in Copenhagen immediately after the Conference. Thus the decision was taken that the Proton-Synchrotron Group should explore the possibility of constructing a 10 GeV proton-synchrotron which, at that time, represented the biggest machine in the world.""
