Abstract

In December 2024, an upgraded data recording and processing system was put into operation at the Yakutsk Extensive Air Shower (EAS) Array, and an additional detector grid with a step of 250 m was deployed, covering the central part of the facility with an area of 0.16 km2. This article presents a description of the modernized software complex for event processing and provides the first results of its operation. As part of the work, a single server database was created, combining data with different formats accumulated over the entire period of operation of the array since 1973. Event processing algorithms were updated and an analysis of the accuracy of reconstructing shower parameters was carried out on the basis of Monte Carlo modeling. The first physical results were obtained on the basis of the new data collection and processing system.
