The first stage of the Baikal-GVD neutrino telescope will be composed of more than two thousand light sensors, Optical Modules (OMs), installed deep underwater in Lake Baikal. We describe developed calibration methods which use OM LEDs, atmospheric muons and discuss the performance of these methods.

The ANTARES detector is the largest neutrino telescope currently in operation in the North Hemisphere, while KM3NeT
is a future new generation neutrino telescope with a volume of a cubic-kilometres that will be located at the bottom of the Mediterranean Sea.
The point-like neutrino search is one of the main goal of the neutrino telescopes, therefore the evaluation of the pointing performance...

The detector of the KM3NeT telescope composed of several thousands digital optical modules is in the process of its realization in the Mediterranean Sea. Each optical module contains 31 3-inch pre-calibrated photomultipliers. Readout of the optical modules and other detector components is synchronized at the level of sub-nanoseconds. The position of the module is measured by acoustic piezo...

The construction of the KM3NeT neutrino telescope in the abyss of the Mediterranean Sea has started. Installation of in total 30 vertical detection units, each supporting 18 optical modules with 31 photomultipliers is foreseen in the first construction phase of the telescope. The KM3NeT timing calibration uses the optical system to send and fan-out an onshore clock signal, derived from a GPS...

Since almost a century photomultipliers have been the main sensors for photon detection in nuclear and astro-particle physics experiments.
In recent years the search for cosmic neutrinos gave birth to enormous size experiments (Kamiokande, Super-Kamiokande, etc.) and even kilometric scale experiments as ICECUBE, Antares, and the future KM3NeT.
A very large volume neutrino telescope requires...

As has been demonstrated by the first generation of neutrino telescopes Antares and IceCube, precise knowledge of the photon detection efficiency of optical modules is of fundamental importance for the understanding of the instrument and accurate event reconstruction. Dedicated test benches have been developped to measure all related quantities for the Digital Optical Modules of the KM3NeT...

KM3NeT is a network of deep-sea neutrino telescopes to be deployed in the Mediterranean Sea, that will perform neutrino astronomy and oscillation studies. It consists of three-dimensional arrays of thousands of optical modules that detect the Cherenkov light induced by charged particles resulting from the interaction of a neutrino with the surrounding medium.
The performance of the...

The IceCube Neutrino Observatory deployed 5160 digital optical modules (DOMs) in a cubic kilometer of deep ice below the South Pole that record the Cherenkov light of passing charged particles. A good understanding of the ice is crucial to the quality of calibration and event reconstruction. While the optical properties of the undisturbed ice are reasonably well understood, the properties of...

The deep-sea neutrino telescope in the Mediterranean Sea, being prepared by the KM3NET
collaboration, will contain thousands of optical sensors to readout. The accurate knowledge of the optical properties of deep-sea water is of great importance for the neutrino event reconstruction process. In this study we describe our progress in designing an experimental setup and studying a method to...
