English translation of the Joint Institute for Nuclear Research journal Fizika Elementarnykh Chastits i Atomnogo Yadra. The journal was founded in December 1970. This translation journal appears simultaneously with the original Russian-language edition, the most influential physical reviews journal. Published by leading physicists from member countries of the Dubna Joint Institute for Nuclear Research, as well as scientists from other countries, review articles in this eminent journal examine elementary particle physics, problems of vacuum in quantum field theory (including condensed matter problems, symmetries), in physics, string theories and gravity, nuclear physics, automatic processing of experimental data, accelerators and related instrumentation.TOPICS COVERED: automatic processing of experimental data; accelerators and related instrumentation; accelerator-driven transmutation technologies; energy production (hybrid reactors); accelerator-driven neutron sources; high-power accelerators.
