Open Day

Saturday 25 April 1964 was the occasion of another CERN 'open day', when, between 2 p.m. and 6 p.m., all those who worked at CERN had been invited to come, with their families and friends, to look around. Most areas of the site were accessible, and neither of the two particle accelerators was in operation during the visit. Special arrangements were made to allow people to see part of the tunnel housing the proton synchrotron and the machine room of the synchro-cyclotron.
