For much of the early years the focus of a large part of the school was designing, re-designing and building a cyclo-synchrotron that in its final intended form was to produce a beam of 10.6 GeV protons for nuclear physics research. Designed to be a world class research machine it was referred to within the school as "The Big Machine". Due to shifting goalposts and huge costs the cyclo-synchrotron was never completed. The small 7.7 MeV cyclotron designed to function as the proton injector was completed in 1955, and the large homopolar generator intended to power the system was first operated in 1962, but by this time work on "The Big Machine" itself had been abandoned.
