MLIT specialists at 27th JUNO collaboration meeting Nikita Balashov, a first-category software engineer of the Meshcheryakov Laboratory of Information Technologies, and MLIT trainee researcher Dmitrii Shpotya participated in the latest meeting of the international collaboration of the JUNO experiment. The event took place on 19-23 January 2026 at Wuhan University in China. At the 27th collaboration meeting, a wide range of issues related to the current state of the JUNO detector and its performance, as well as general collaboration affairs, were discussed. Plans for physics data taking and processing, including computing resource usage planning, were also considered. Nikita Balashov presented an overview of the current state of the JINR data center, which serves as a Tier1 grid site in the JUNO experiment’s distributed computing infrastructure. The provided computing resources and data storage systems, as well as their usage in 2025, were examined. Particular attention was paid to the introduction of a new dCache-based disk storage and global network connectivity issues. Dmitrii Shpotya delivered a talk on a web system and a database developed for the offline validation of JUNO experiment runs. The system enables to analyze data quality at the level of separate runs and make decisions about excluding “bad” runs from further analysis. The service’s major functions and its use in the work of shifts were covered. We previously wrote about MLIT’s participation in the JUNO project. For reference: The primary objective of the JUNO experiment is to determine neutrino mass ordering. Thanks to the enormous size of the liquid scintillation detector and the high precision of energy measurements, the experiment opens up broad opportunities for scientific research, from precision measurements of the mixing parameters of the Standard Model lepton sector, geoneutrino registration, and observations of neutrinos from supernovae to the search for new physics, including proton decay. The first result of the experiment, based on a 59-day dataset, was presented in November 2025. The parameters of neutrino oscillations Δm²₂₁ and sin²θ₁₂ were measured with record precision.
