Upgrade of the Facility of the DANSS Experiment

The DANSS facility to study reactor antineutrino fluxes is located in the heart of the Kalinin Nuclear Power Plant (KNPP), several metres away from the reactor core. DLNP physicists investigate neutrino oscillations and search for sterile neutrinos whose possible existence is indicated by recent calculations of French researchers. Not long ago, a previously scheduled upgrade of the facility started which will allow increasing its efficiency and gaining new results in one of the most promising fields of modern physics.

Tsvetan Vylov as a Prominent Scientist and Science Administrator

Today, we commemorate the 80th birthday of Doctor of Physics and Mathematics, Professor Tsvetan Vylov, a prominent scientist and science administrator. The Bulgarian physicist Tsvetan Dimitrov Vylov started his career at JINR in 1968 at the Experimental Department of Nuclear Spectroscopy and Radiochemistry (EDNSR). He was involved in precision spectrometry of nuclear radiation and initiated a new research direction at JINR, non-accelerator neutrino physics. In 1984, he became a head of EDNSR, in 1988 — a director of the Laboratory, and in 1992 — a vice-director of JINR.

The first day of the 21st Baikal JINR-ISU Summer School

The first day of the 21st Baikal JINR-ISU School organized by the Dzhelepov Laboratory of Nuclear Problems and Irkutsk State University is over. This year, we are constrained to organize this annual School online. Despite all the constraints, we have gathered about 30 students from several countries who are eager to listen to lectures on particle physics and astrophysical neutrinos and to give their own presentations. Looking forward to five more days of lectures, talks, and questions!

The 2020 DLNP Research Award Competition: Boris Popov about the Research of Hadron Production in Proton−Nucleus Interactions in NA61/SHINE (CERN) to Precisely Predict Neutrino Spectra and Fluxes in T2K (Japan)

Recently, the results of the 2020 Research Award Competition of the Dzhelepov Laboratory of Nuclear Problems have been announced. The DLNP Group of Scientific Communication spoke with the winners about their research. One of the two second Prizes was awarded to the authors: S. A. Bunyatov, A. V. Krasnoperov, B. A. Popov, V. V. Tereshchenko from the Experimental Department of Multiple Hadronic Processes and V. V. Liubushkin from the Section of Elementary Particles for the series of papers “Research of hadron production in proton−nucleus interactions in the NA61/SHINE experiment (CERN) to precisely predict neutrino spectra and fluxes in the T2K accelerator experiment (Japan)”. We talked to Boris Albertovich Popov about the research behind this series.

Krzysztof Siemek about the First Results of the Experiment on Development of a Coating with Unique Radiation Hardness Properties

Recently, an article about the first results of the experiment on development of a coating with unique radiation hardness properties has been published on the website “Nauka — RIA Novosti”. The research is being performed by scientists from Tomsk Polytechnic University (TPU) in cooperation with the Weinberg Research Center (WRC, TPU) and the Dzhelepov Laboratory of Nuclear Problems (DLNP, JINR). 

May Issue of GNN Monthly Published (News from Large Neutrino Telescopes)

Mark Shirchenko Was a Guest of “Brunch with a Scientist” at the Polytechnic Museum

This Sunday, the researcher of the Dzhelepov Laboratory of Nuclear Problems Mark Shirchenko took part in the popular event of the Polytechnic Museum “Brunch with a Scientist”. We were eager to know how it went on.

A Series of Seminars to Commemorate Tsvetan Vylov Will Be Held at DLNP

In 2021, Tsvetan Vylov (13.07.1941—13.12.2009) would have celebrated his 80th birthday. He is a prominent Bulgarian physicist who contributed a lot to establishing the spectroscopy “school” at JINR and who, among others, initiated the experimental DLNP neutrino programme as we know it today. To celebrate his 80th birthday, a series of seminars will be organized at the Experimental Department of Nuclear Spectroscopy and Radiochemistry which he headed in 1984−1988. The first talk will be given by A. Kh. Inoyatov, Doctor of Physics and Mathematics, who had been working under the guidance of Tsvetan Vylov for a long time.    

The Head of the Borexino Group at JINR Oleg Smirnov about the Receiving the Giuseppe and Vanna Cocconi Prize of the European Physical Society

BOREXINO“The needle is in an egg, the egg is in a duck, the duck is in a hare, the hare is in a chest”, this fairy tale imagery is evoked when one thinks of the detector structure of the Borexino experiment. The nylon vessel with a radius of 4 m contains almost 300 t of liquid scintillator. The stainless-steel sphere with a radius of 8.5 m encloses it. About 700 t of buffer fluid is between the nylon bag and the sphere. The entire construction is immersed into the tank with 2.5 t of ultrapure water. The detector itself is shielded by the massive Italian mountain Gran Sasso.
