Yakovlev arXiv: 1908.05533 ยท 2019-08-16 ## TL;DR This paper discusses the development of inter-cluster time synchronization systems for the Baikal-GVD neutrino telescope, enabling accurate event merging across independent detector clusters in a large underwater Cherenkov detector. ## Contribution It introduces the design and implementation of inter-cluster synchronization systems crucial for multi-cluster event analysis in the Baikal-GVD detector. ## Key findings - Successful synchronization across clusters demonstrated - Enhanced accuracy in multi-cluster event reconstruction - Foundation for future large-scale neutrino detection ## Abstract Currently in Lake Baikal, a new generation neutrino telescope is being deployed: the deep underwater Cherenkov detector of a cubic-kilometer scale Baikal-GVD. Completion of the first stage of the telescope construction is planned for 2021 with the implementation of 9 clusters. Each cluster is a completely independent unit in all the aspects: triggering, calibration, data transfer, etc. A high-energy particle might leave its trace in more than a single cluster. To be able to merge events caused by such a particle in more clusters, the appropriate inter-cluster time synchronization is vital. --- Source: https://tomesphere.com/paper/1908.05533
