Abstract
Abstract Neutrino telescope Baikal-CVD is a deep-underwater Cherenkov detector of elementary particles of the 1-km3 scale, which has been developed beginning from 2016 in Lake Baikal. The telescope is assembled from separate blocks (clusters of optical modules), which makes it possible to perform scientific research even at early stages of its development. In the 2021 configuration, the detector contains eight clusters with 2304 optical modules in total and is the largest neutrino telescope in the Northern hemisphere. The design and main characteristics of the Baikal-GVD data acquisition system are described, the problems of deep-underwater engineering associated with the development of the detector are considered, and some physical results obtained on the facility are presented
