In August 2025, 10 years after the beginning of the construction, the creation of the JUNO largest liquid-scintillator neutrino detector in Guangdong (China) was successfully completed. Just two months after the start of data-taking, the JUNO collaboration presented its first physical data. They demonstrated record-breaking precision that surpassed achievements based on data of other experiments taken for years.

The semiconductor pixel hybrid modules of the High Granularity Timing Detector (HGTD) will be used in the ATLAS experiment during high-luminosity data-taking periods (Run 4 and later), reaching luminosities up to ${7,5} \times{10}^{34} {см}^{−2}{с}^{−1}$.

The DLNP JINR compact precision laser inclinometers were installed in Kamchatka in 2022 for joint research and data processing with the Kamchatka Branch of the Geophysical Survey of the Russian Academy of Sciences and the Vitus Bering Kamchatka State University.

The report is devoted to the study of solar hep-neutrinos and diffuse supernova neutrino background (DSNB) in the Borexino experiment. The peculiarities of studying solar hep-neutrinos, which have the highest energy and the lowest flux among all neutrinos from the Sun, will be discussed. Constraints on the hep-neutrino flux are presented, based on Borexino detector data on neutrino-electron elastic scattering and neutrino interaction with carbon nuclei.

The report focused on the problem of event detection in experimental setups for dark matter searches. Using the DEAP-3600 detector as an example, it was shown that design features of the experimental setup can lead to a degradation in the quality of event analysis or to the emergence of an additional contribution to the detector's background model.

The report aims to familiarize the audience with the properties of diamonds synthesized in laboratory and industrial settings, the capabilities of JSC "Diatek" (the largest diamond synthesis company in Europe) in the production and processing of diamond materials, and the promising application areas for mono- and polycrystalline diamond.
28.10.2025
The report will outline the principles of post-growth engineering of synthesized diamond monocrystals (plates) to create nitrogen-vacancy centers using charged particle beams. It will demonstrate the capabilities of positron annihilation spectroscopy for identifying defects in such plates and present work on the development of quantum measurement devices based on them.

Twisted quantum states of particles possess a vortex wave front structure and carry quantized angular momentum along the propagation direction. Such states have already been successfully realized for photons, as well as electrons, neutrons, and ions at nonrelativistic energies.

This report will consider the interactions between optical radiation and biological objects. Particular attention will be paid to the main types of elastic scattering, as well as the components of biological objects that determine the scattering and absorption of optical radiation. Examples of the practical application of optical methods in biology and medicine will be given. The report concludes with a discussion of the main trends in the development of modern biophotonics.
08.10.2025
The report presented a method for diagnosing the orbital angular momentum (OAM) of twisted massive waves, electrons and light ions, based on their diffraction at circular and triangular apertures in the far field.
02.10.2025
A new type of data acquisition system is being developed for the SPD experiment, implemented as a triggerless system. The system components provide continuous data streaming and preprocessing for the subsequent operation of the online filter system.
