TL;DR
The Lake Baikal Neutrino Experiment has operated since 1998, upgraded to NT200+, and is progressing towards a km3-scale detector, with recent results in neutrino detection and acoustic methods for ultra-high-energy neutrinos.
Contribution
This paper reviews the long-term operation, recent physics results, and technological advancements towards a large-scale neutrino detector in Lake Baikal.
Findings
Selected astroparticle physics results from NT200
Progress in acoustic detection of UHE neutrinos
Deployment of a km3-prototype string with new technology
Abstract
We review the status of the Lake Baikal Neutrino Experiment. The Neutrino Telescope NT200 has been operating since 1998 and has been upgraded to the 10 Mton detector NT200+ in 2005. We present selected astroparticle physics results from long-term operation of NT200. Also discussed are activities towards acoustic detection of UHE-energy neutrinos, and results of associated science activities. Preparation towards a km3-scale (Gigaton volume) detector in Lake Baikal is currently a central activity. As an important milestone, a km3-prototype string, based on completely new technology, has been installed and is operating together with NT200+ since April, 2008.
