U-70

The U-70 is a proton accelerator in Protvino that drives particles to energies of 76 GeV as they travel along a circular path spanning about 1,500 meters (4,920 feet). The facility uses a linear accelerator stage to boost protons to initial energy levels before they enter the main ring.

The facility began operations in 1967 as the Soviet Union's leading particle accelerator and represented a major step forward in nuclear physics research. It demonstrated the country's scientific capability during an era of intense international competition in physics.

The facility brings together researchers from across Russia and international partners to pursue high-energy physics experiments in collaboration. Their discoveries and findings are shared through scientific publications that contribute to the global understanding of particle behavior.

The facility operates according to regular cycles as it continuously accelerates and directs particle beams through the ring system. Visitors should understand that this is an active research center where access may be limited depending on ongoing experiments.

A memorable incident at the facility occurred in 1978 when a researcher was exposed to a concentrated proton beam during maintenance work. The event is notable because the person survived the exposure, making it an important case study in radiation safety history.
