Japanese synchrotron yields 10‐GeV protons Available to Purchase

The first accelerator for high‐energy physics in the Far East was recently dedicated at the KEK laboratory in Tsukuba science city, 60 km northeast of Tokyo. The proton synchrotron, whose construction began in 1971, has exceeded its initial design energy of 8 GeV on 19 March, when it reached over 10 GeV. After the main ring power supply and cooling capacity are modified, the machine is expected to reach a peak energy of 12 GeV.
