MLIT young scientists at 28th JUNO collaboration meeting Trainee researchers of the Meshcheryakov Laboratory of Information Technologies presented the results of their work at the 28th meeting of the international collaboration of the JUNO (Jiangmen Underground Neutrino Observatory) experiment. The meeting is being held on 20 – 24 July 2026 at the Institute of High Energy Physics (IHEP) in Beijing. Dmitrii Shpotya spoke about the elaboration of an interface for the channel quality control system in the ODM platform of the JUNO experiment. The talk considered the development status of the JUNO experiment’s channel quality control system. The system is designed to monitor the state of the detector’s channels (photomultipliers), to identify problematic channels, and store information about their state throughout the entire period of the experiment. Key system changes, including new tools for channel quality analysis, database reorganization, and plans for further system development were discussed. Albert Dzakhoev enlarged upon a prototype of the real-time user task monitoring system, jsub-monitor, for the JUNO experiment. The service integrates telemetry collection on compute nodes, a web interface for the live viewing of the status of individual tasks and task groups, and task activity classification to detect freezing. The report covered the service architecture, its current capabilities and overhead costs measured on a testbed, as well as future development plans. A talk by Egor Tsamtsurov was devoted to the development status of JSUB, a system for describing, launching, and managing JUNO computing tasks via a unified interface. A basic user scenario and the automation of publishing workgroup software to compute nodes were shown. The transfer of part of the workload from a local cluster to a distributed computing infrastructure by launching tasks through DIRAC was demonstrated using a real JUNO workflow. Egor Tsamtsurov also discussed the release of the new version of JSUB, the introduction of development, testing, and release procedures, and future plans. The collaboration meeting discusses the status of the JUNO detector and its current performance, plans for data taking and processing (including computing resource usage planning), and requirements for future physics results and publications. Background information. 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.
