Dzhelepov Laboratory of Nuclear Problems
Joint Institute for Nuclear Research
Dzhelepov Laboratory of Nuclear Problems (DLNP) of Joint Institute for Nuclear Research (JINR) is a multi-disciplinary laboratory leading dozens of research activities in particle physics, neutrino physics, astrophysics, development of accelerator technologies and detector construction.
DLNP has the widest and most diversified ever Neutrino Program in the world. Renowned nuclear physicist Bruno Pontecorvo worked in the lab for more than 40 year and established a Neutrino School in JINR. Nowadays, DNLP fellows work on about a dozen different neutrino experiments covering accelerator, reactor, solar, astrophysical neutrino and neutrinoless double beta decay experiments. There is also lots of activity in theoretical and phenomenological activity in the neutrino field.
DLNP is a dynamic laboratory working at frontiers of particle physics, neutrino physics and technologies. There are more than 650 employers in DLNP. DNLP is highly competent in many fields of physics, including medical and biological studies. Currently, DLNP is increasing even further in its activity, attracting young scientists to its state-of-the-art neutrino projects.
In 2016, Dubna physicisists within the Daya Bay Collaboration achieved a remarkable result – the first measurement of theta13 lepton mixing angle, unknown by that time. This result was acknowledged by the Breakthrough Prize in Fundamental Physics 2016.
Now DNLP’s flagship project is the construction of a cubic kilometer detector in Lake Baikal. Even now Baikal Neutrino Telescope is the largest neutrino telescope in the nothern hemisphere. This spring sees the installation install of two more clusters thus reaching about 50% of its designed volume. The key advantage of Baikal Neutrino Telescope is a very good angular resolution of arrival direction of ultra high energy neutrio - instrumental for the neutrino astronomy.
Another important activity is related to experiments at Kalinin Power Plant, with which DLNP has an exclusive agreement to conduct experiments. These include DANNS, an experiment searching for a sterile neutrino and developing technique for the reactor monitoring; nuGEN, an experiment precisely measuring coherent scattering of neutrino off a nucleus; and GEMMA, an experiment setting up the most stringent limits on neutrino magnetic moments.
DNLP also plays a major role in international neutrino research, with a role in studies including: BOREXINO, a solar neutrino experiment, which has already seen remarkable results have been achieved; JUNO, the largest reactor antineutrino experiment ever, where DNLP plays a crucial role building the high voltage units and developing techniques for mass tests of photomultipliers (PMTs), as well as constructing the muon veto system; SuperNEMO and GERDA - neutrinoless double beta experiments.
