V.P. Dzhelepov, renowned Russian scientist, was one of the founders of the Institute of Nuclear Problems (1948) and later of the Joint Institute for Nuclear Research in Dubna, where he was director (1956-1988) and since 1988 honorary director of the Laboratory of Nuclear Problems.

His long path in science is marked by many bright results. He constructed the then (1949)world largest 680 MeV proton synchrocyclotron. He obtained pioneer data in nucleon-nucleon and pion-nucleon interactions, in capture of negative muons by protons, in electron decay of negative pions; new results were achieved in multiple production of strange and neutral particles and hypercharge-exchange reactions in high-energy physics experiments. He was the first to obtain the fundamental, now classical, experimental results in physics of muon molecules and of muon-catalysed nuclear fusion of heavy hydrogen isotopes.

It is he who initiated and supervised the construction of Russia's first clinico-physical complex based on the synchrocyclotron of the Laboratory of Nuclear Problems for proton treatment of cancer and for space medicine.

He was a corresponding member of the Russian Academy of Sciences, for many decades one of the leaders of the Nuclear Physics Division of the Russian Academy of Sciences.

Being a member of IUPAP commissions, ICFA and editorial boards of highly authoritative scientific journals, he made a substantial contribution to the development of the international scientific cooperation. Many eminent scientists in Russia and other countries learned much by working with V.P.Dzhelepov.

LNP consists of 9 scientific divisions, a self-financing scientific Phasotron division, a designing division, an experimental machine shop, and 3 auxiliary divisions. A total of 690 people work at the Laboratory.

The scientific activities of the Laboratory cover

  • experimental investigation in particle physics (at high, low and intermediate energies);
  • investigation of nuclear structure (including relativistic nuclear physics and nuclear spectroscopy);
  • study of condensed matter properties;
  • biological and medico-biological investigations;
  • development of new accelerators.
