The 70-GeV proton synchrotron

The parameters of the 70-GeV proton synchrotron were published in the Proceedings of the International Conference on High Energy Accelerators in 1963 (see Vladimersky et al., "70-GeV Proton Synchrotron," Proceedings of the International Conference on High Energy Accelerators, Dubna, M. Atomizdat, 1964). The accelerator status during the period before its startup was reported at the Frascati conference in 1965, as well as at the Washington and Cambridge conferences in 1967. The accelerator began to work in 14 October 1967. Since then particle dynamics has been investigated, the systems of the slow proton beam guiding onto the internal targets were put into operation, and secondary beams were formed. Brief information on the present accelerator status is given.
