Status of the early construction phase of Baikal-GVD
The 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
The data acquisition system for Baikal-GVD
Baikal-GVD will be a neutrino telescope at the cubic-kilometer scale in Lake Baikal. The first out of 10-12 clusters of the first phase of GVD has been deployed and commissioned in April 2015. This paper describes design and implementation of the dataacquisition system of GVD. © Owned by the authors, published by EDP Sciences, 2016
Search for neutrinos from gamma-ray bursts with the Baikal neutrino telescope NT200
We present the results of our search for neutrino events coinciding in time and direction with gamma-ray bursts (GRBs) with the Baikal underwater neutrino telescope NT200. No events confirming a neutrino accompaniment of GRBs have been detected. Model-independent limits (Greens function) on the neutrino flux from GRBs have been obtained. For the Waxman-Bahcall neutrino spectrum, the limit on the neutrino flux from a GRB has been found to be E 2 ν Φ ν ⩽ 1.1 × 10−6 GeV cm−2 s−1 sr−1
