The Cosmotron at the Brookhaven National Laboratory,Long Island,was the first proton sychrotron to come into operation,in 1952. The protons were first accelerated to 3 MeV in a Van de Graaf generator (the cylindrical tank in the foreground). They then travelled through the pipe to the "doughnut" of the main accelerator,where they were raised to an energy of 3 GeV. The Cosmotron ceased operations in 1966 | |
