Novel Algorithm for Qualitative and Quantitative Material Analysis by the K-Edges for Photon-Counting Computed Tomography

Researchers of our laboratory Georgy Shelkov, Vladislav Rozhkov and Rostislav Sotenskii together with MSU scientists developed the algorithm for quantitative and qualitative material analysis by the K-edges for photon-counting computed tomography.

Monte Carlo programs for small-angle Bhabha scattering

The article titled “Monte Carlo programs for small-angle Bhabha scattering” was published in Chinese Physics C by a team of authors from the JINR Laboratory of Nuclear Problems, the JINR Laboratory of Theoretical Physics and Dubna State University. Among the authors are staff members from the Department of Colliding Beams of our laboratory I. R. Boyko, L. V. Kalinovskaya, A. A. Kanpf, R. R. Sadykov, and V. L. Yermolchik.

Dmitry Ponomarev: “Venedikt Petrovich Dzhelepov for me is an example of an excellent organiser and brilliant scholar who made a significant contribution to world science”

At the meeting of the Scientific and Technical Council of the Dzhelepov Laboratory of Nuclear Problems on 8 December 2023, it was announced that the Dzhelepov Scholarship for young scientists of the Laboratory in 2024 was awarded to Dmitry Vladimirovich Ponomarev, a junior researcher in Sector 2 of Weak Interactions of the DLNP Department of Nuclear Spectroscopy and Radiochemistry. The DLNP Group of Scientific Communications talked with Dmitry Ponomarev about his current work and plans for 2024.

Alina Vishneva: “Saying ‘neutrino physics’, we are implying ‘Bruno Pontecorvo’”

On 8 December 2023, at a meeting of the Scientific and Technical Council of the Laboratory of Nuclear Problems, the results of the competition for the 2024 Bruno Pontecorvo Scholarship for Young DLNP Scientists were announced. The winner of the competition was Alina Vadimovna Vishneva, a researcher of Sector 3 of Experimental Neutrino Physics at the DLNP Department of Particle Physics.

New results of precision measurement of muon anomalous magnetic moment

In October 2023, the international Muon g-2 collaboration published an article in Phys. Rev. Lett. reporting results of the experiment on precision measurements of muon anomalous magnetic moment at Fermilab (USA). Being a part of the collaboration, the group of scientists from DLNP JINR (V. A. Baranov, V. P. Volnykh, V. N. Duginov, V. A. Krylov, N. A. Kuchinsky, N. V. Khomutov) took part in the creation of the prototype of a tracking detector and in development of data acquisition and visualization system.

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.
