Survey “Reaching Unreachable Heights”

Dear colleagues, our beloved friends! In a state of great excitement, we would like to inform you that starting from 2024, the Joint Institute for Nuclear Research is going to set more ambitious goals and rise up to unreachable heights of scientific advances thanks to our new carefully elaborated and painstakingly thought-out seven-year development plan. We are preparing for implementation of breakthrough ideas in science and technology which will allow us to broaden scientific boundaries, get new knowledge about the constitution of nature and design novel practical tools to increase the quality of life.

Chronicles of the 2023 Baikal Expedition. Week 5

March 19. Day 31 Today, assembling of Strings 2, 6 and 9 of Cluster 11 has proceeded. New Chinese orange buoys much heavier than those usually used were mounted on String 6. Specialists from Optosvyaz have checked optical fibre of the recently laid bottom cable – all six fibres are in order!

International Collaboration FASER at CERN Detects First Neutrinos Made by Particle Collider

The FASER experiment has for the first time detected subatomic particles called neutrinos created by a particle collider. The discovery promises to deepen scientists’ understanding of the nature of neutrinos, first spotted in 1956, which are the most abundant particle in the cosmos and a key participant in the process that makes stars burn. The work could also shed light on cosmic neutrinos that travel large distances and collide with the Earth, providing a window on distant parts of the cosmos.  

Chronicles of the 2023 Baikal Expedition. Week 4

March 12. Day 24 The deployment of new clusters and upgrade of those previously installed are proceeding. The cause of the fault of the string module acoustic line on String 4 of Cluster 2 has been identified at the shore lab. All the modules of String 8 and 4 of Cluster 1 are installed and tested. Today, the bottom cable laying has been interrupted due to the breakage of the ice-cutter. It is being repaired.

A Catalogue of All Detected and Simulated Events in the ATLAS Experiment at CERN Compiled

Annually, several billions of particle interactions are detected in the ATLAS experiment at the LHC at CERN. These events are processed, analyzed, and even larger simulated data samples are generated for them. To track the location of each event record and also to be able to search for and retrieve specific events during in-depth investigations, the ATLAS EventIndex catalogue has been compiled. The EventIndex project results have been recently published in a high-ranking scientific journal Computing and Software for Big Science.  

Chronicles of the 2023 Baikal Expedition. Week 3

March 5. Day 17 Today, the installation of Cluster 11 has proceeded — the bottom and the middle sections of String 1 were assembled, the anchor of String 8 was installed and the string was mounted right to the bottom central module. String 7 was also assembled right to the bottom central module, and a hand winch was installed on String 2.

Chronicles of the 2023 Baikal Expedition. Week 2

February 25. Day 9 The first winch with the cable wound up was mounted near the maina of a new string of a new cluster, and the anchor was brought to it. Everything is ready for the assembly. The testing of new optical modules got underway. The delivery of new optical modules from Baikalsk goes on. Today, another 140 items have arrived.  A large group of colleagues from INR have come to the shore. Now we can make up the third assembling team.

First Results of the Baikal-GVD Neutrino Experiment Searching for Astrophysical Neutrinos Published

The article of the Baikal-GVD collaboration has been published in the authoritative science journal Physical Review D. The first results of the search for astrophysical neutrinos based on the data accumulated by Baikal-GVD, the Baikal Deep Underwater Neutrino Telescope, were announced. The astrophysical neutrino flux earlier detected by the Antarctic Neutrino Telescope IceCube was confirmed. The Baikal Neutrino Telescope is one of the Russian projects at the mega science level. The Baikal-GVD Telescope was ceremonially launched in March 2021 with the participation of the Minister of Higher Education and Science of the Russian Federation Valery Falkov.

Chronicles of the 2023 Baikal Expedition. Week 1

February 17. Day 1 Today, the Baikal expedition to construct the neutrino telescope has been launched. The first group of scientists and specialists under the guidance of Igor Belolaptikov have arrived at the 106th km of the Circum-Baikal Railway. May the ice be strong and the weather fine!

The Cousins Dzhelepov: Both Physicists and Sportsmen

For over 20 years, the tennis tournament of the Cousins Dzhelepov has been held in Dubna. The cousins Venedikt Petrovich (1913–1999) and Boris Sergeevich (1910–1998) were avid for tennis, and they did a lot to promote it. Both were renowned physicists, corresponding members of the AS of the USSR and RAS, participants of the Atomic Programme of the USSR under the guidance of I. V. Kurchatov, outstanding science administrators, developers of research facilities, authors of many scientific papers. They graduated from Leningrad institutes. The son of B. S. Dzhelepov recalled that both cousins attended the nuclear bomb test on Novaya Zemlya and undersigned the final protocol.
