摘要

Abstract

The development of the deep underwater neutrino telescope BAIKAL-GVD involves the creation of equipment for regular long-term monitoring of inherent optical properties (IOP) of the aquatic environment within the effective volume of the telescope. Regular monitoring of IOP provides not only an increase in the accuracy of retrieving neutrino energy and direction, but also unique data for limnological studies. The paper describes the design of BAIKAL-5D devices developed to solve this problem and considers the methods and algorithms for in situ monitoring of IOP used in these devices. The sources of instrumental error in measuring the light absorption and scattering in water are examined and the necessary corrections are determined. Some results of measuring IOP of the deep waters of Lake Baikal using BAIKAL-5D devices are presented.
