On April 11, 1957, the largest particle accelerator in the world was inaugurated in Dubna (Soviet Union)

In 1956, the USSR Academy of Sciences signed an agreement for the foundation of the Joint Institute for Nuclear Research (JNRI). In time, the JNRI became one of the most important international research centres for nuclear physics, particle physics, and condensed matter physics.

It is located in Dubna and is dedicated to the study and development of the natural sciences and the fundamental properties of matter.

It is staffed by 5,500 employees, 1,200 researchers, including 1,000 PhDs from EU Member States, as well as some eminent and well-known scientists from UNESCO, CERN, the United States, and others.

The institute has been involved in the discovery of some of the elements of the periodic table: rutherfordium (1964), dubnium (1967), seaborgium (1974), flerovio (1999), livermorio (2001), nihonium (2004), muscovio (2004), organeson (2006) and teneso (2010).

On 11 April 1957, the world's largest particle accelerator for studying the fundamental properties of matter was inaugurated in Dubna (Soviet Union). It is a vast international research laboratory, mainly devoted to particle physics, heavy ion physics, synthesis of transuranic elements, and radiobiology.

The synchrophasotron, or heavy particle synchrotron, was capable of accelerating protons to a record energy of 10 GeV (10 billion electron volts).

Some of the most renowned physicists of the 20th century worked here, such as Nikolai Bogoliubov, and Georgy Fliorov, founder of the Flevov Laboratory of Nuclear Reactions, element 114 Flerovius is named after him.
