Protons guided by magnets in synchrotron

Unusually uniform electrical grade steel has helped make possible a new concept in smashing the atom, and will make possible the gathering of much more information on these basic building blocks of the universe. The new concept, called strong focusing, depends on huge magnets holding protons on course and using these particles to hit and break the nuclei of other atoms. The nuclear properties can then be observed and studied. For this purpose, a mammoth new proton synchrotron is being built at Brookhaven National Laboratory, Upton, N. Y.
