Recently, Russia opened the northern hemisphere’s largest deep-water trino telescope “Baikal-GVD” in Lake Baikal to record the flow of ultra-high energy neutrinos from celestial bodies, study geophysics, hydrology and freshwater biology phenomena, and explore the universe The production and evolution process.
The neutrino telescope is an ultra-large detection device that can measure very rare ultra-high-energy neutrinos from the depths of the universe and determine the location of their corresponding celestial body sources. In order to avoid interference from other signals, it is usually placed in the depths of the ice layer or on the seabed and lake bottom. “Baikal-GVD” started in 2015 and was constructed in collaboration with scientists from the Czech Republic, Germany, Poland, Russia and Slovakia. The floating observatory is composed of hundreds of spherical modules made of glass and stainless steel. A single module is 1 cubic meter in size. These modules are connected by a set of cables and currently occupy a volume of 500 cubic meters.
