Design and Validation of High-Reliability Acquisition Electronics for KM3NeT Neutrino Telescope

Original language description

The KM3NeT Collaboration is developing two deep-sea neutrino telescopes in the Mediterranean Sea. These telescopes use digital optical modules equipped with photomultipliers and acquisition electronics. Mounted on vertical strings, thousands of these modules are already in operation. Once completed, the telescopes will feature over six thousand synchronized modules, creating one of the world’s most advanced detection networks. This work presents the strategies in the design, upgrade, and manufacturing of the acquisition electronics boards for KM3NeT to obtain high-reliability products that can operate in deep sea conditions, 2500 meters deep in the case of ORCA and 3500 meters in the case of ARCA. Various methods, including FIDES analysis, Design for Manufacturability (DfM) analysis, Highly Accelerated Life Tests (HALT), Highly Accelerated Stress Screening (HASS), and functional test benches are employed. In addition, the ancillary board developed for the debugging of produced boards with problems of synchronization is presented. The validation workflow follows a structured process for upgrading any acquisition board, integrating iterative steps to ensure performance and robustness. By adopting an agile-inspired approach, the methodology prioritizes efficiency and adaptability, fulfilling the tight production planning of the experiment, while maintaining high-reliability standards.
