The Baikal neutrino experiment: Status, selected physics results, and perspectives

AbstractWe review the status of the Baikal neutrino telescope, which is operating in Lake Baikal since 1998 and has been upgraded to the 10 Mton detector NT200+ in 2005. We present selected physics results on searches for upward going neutrinos, relativistic magnetic monopoles and for very high-energy neutrinos. We describe the strategy of creating a detector on the Gigaton (km3) scale at Lake Baikal. First steps of activities towards a km3 Baikal neutrino telescope are discussed.

Baikal neutrino telescope—An underwater laboratory for astroparticle physics and environmental studies

AbstractWe review the status of the Baikal Neutrino Experiment. The Neutrino Telescope NT200 is operating in Lake Baikal since 1998 and has been upgraded to the 10 Mton detector NT200+ in 2005. We present selected results concerning astroparticle physics as well as results of environmental studies. We describe the strategy of creating a Gigaton (km3) scale neutrino detector at Lake Baikal. First steps of activities towards a km3 Baikal neutrino telescope, including the development of acoustic high-energy neutrino detection methods are discussed.

The prototype string for the km3-scale Baikal neutrino telescope

AbstractA prototype string for the future km3-scale Baikal neutrino telescope has been deployed in April, 2008, and is fully integrated into the NT200+ telescope. All basic string elements–optical modules (with 12″/13″ hemispherical photomultipliers), 200 MHz FADC readout and calibration system–have been redesigned following experience with NT200+. First results of in-situ operation of this prototype string are presented.

Hardware and first results of TUNKA-HiSCORE

AbstractAs a non-imaging wide-angle Cherenkov air shower detector array with an area of up to 100 km2, the HiSCORE (Hundred⁎i Square km Cosmic ORigin Explorer) detector concept allows measurements of gamma rays and cosmic rays in an energy range of 10 TeV up to 1 EeV. In the framework of the Tunka-HiSCORE project we have started measurements with a small prototype array, and planned to build an engineering array (1 km2) on the site of the Tunka experiment in Siberia. The first results and the most important hardware components are presented here.

The TAIGA experiment: From cosmic-ray to gamma-ray astronomy in the Tunka valley

AbstractWe present physical motivations and advantages of the new gamma-observatory TAIGA (Tunka Advanced Instrument for cosmic ray physics and gamma-ray astronomy). TAIGA will be located in the Tunka valley, 50 km to the west of Lake Baikal, at the same place as the integrating air Cherenkov detector for cosmic rays Tunka-133. The TAIGA array is a complex, hybrid detector for ground-based gamma-ray astronomy for energies from a few TeV to several PeV as well as for cosmic ray studies from 100 TeV to several EeV. The array will consist of a wide angle Cherenkov array – TAIGA-HiSCORE with 5km2 area, a net of 16 IACT telescopes (with FOV of about 9.72°×9.72°) as well as muon and other detectors. We present the current status of the array construction.

BAIKAL experiment: status report

AbstractWe review the present status of the Baikal Neutrino Project and present the results obtained with the deep underwater neutrino telescope NT-200

Status of the early construction phase of Baikal-GVD

AbstractThe second-stage neutrino telescope BAIKAL-GVD in Lake Baikal will be a research infrastructure aimed mainly at studying astrophysical neutrino fluxes by recording the Cherenkov radiation of the secondary muons and showers generated in neutrino interactions. The prototyping/early construction phase of the BAIKAL-GVD project which is directed towards deployment and operation of the first demonstration cluster has been started in April 2011. An important step on realization of the GVD project was made in 2014 by the deployment of the second stage of the demonstration cluster which contains 112 OMs arranged on five strings, as well as equipment of an acoustic positioning system and instrumentation string with an array calibration and environment monitoring equipment. Deployment of the demonstration cluster will be completed in 2015.
