Inauguration of the Proton Synchrotron

The PS came into operation on 24 November 1959, breaking existing records as the world’s biggest and most powerful particle accelerator. The official ceremony a few months later (you can watch part of it in this 1960 documentary) was a celebration of the technical achievement but also of successful European co-operation that paved the way for progress in the aftermath of World War II. A special issue of the CERN Courier gave more information about the new machine.

A press conference and visit were followed by lunch, then the official inauguration by Niels Bohr, speeches and a reception. The guest list included several hundred eminent scientific and political figures. The back cover of the commemorative brochure also featured VIPs - the men and women who made up the PS team.
