Installation "Troitsk nu-mass"

Installation for measuring the mass of electron antineutrinos in the beta decay of tritium “Troitsk-nu-mass”. The limit on the neutrino mass obtained at this installation remained the best in the world for 15 years. The Troitsk-nu-mass record was broken in 2019. This was accomplished at the KATRIN facility in Germany with the participation of scientists from the Institute for Nuclear Research (INR RAS). The design of the KATRIN installation is a scaled model of the Troitsk-nu-mass experiment, originally proposed by academician V.M. Lobashev.
