“…The calibration laser source [13,14] is located at 1215 m depth and is used for time synchronization between OMs on different strings. High intensity of laser source (up to 6 × 10 13 photons/pulse) allows illumination of OMs at distances more than 200 m from the source.…”

The Prototyping phase of the BAIKAL-GVD project has been started in April 2011 with the deployment of a three string engineering array which comprises all basic elements and systems of the Gigaton Volume Detector (GVD) in Lake Baikal. In April 2012 the version of engineering array which comprises the first full-scale string of the GVD demonstration cluster has been deployed and operated during 2012. The first stage of the GVD demonstration cluster which consists of three strings is deployed in April 2013. We review the Prototyping phase of the BAIKAL-GVD project and describe the configuration and design of the 2013 engineering array.

“…An external calibration laser provides five series of 480 nm light pulses at five fixed intensity levels ranging from approximately 10 12 to 6 Â 10 13 photons/pulse [12], which corresponds to shower energies from 10 PeV to 600 PeV. Distances between the light source and OMs of prototype cluster range from 110 m up to 180 m (see Fig.…”

“…The cluster DAQ system is being tested with the Baikal underwater calibration laser [12], with LED flashers, and atmospheric muons. Two trigger modes are used for muon detection: four-fold coincidences of optical modules on a string (trigger 4/1, event rate 4 Hz), and inter-string two-fold coincidences of two strings (trigger 2/2, event rate 0.5 Hz).…”

a b s t r a c tThe construction of a km 3 -scale neutrino telescope -the Gigaton Volume Detector (GVD) in Lake Baikal -is the central goal of the Baikal collaboration. During the R&D phase of the GVD project in 2008-2010 years the basic elements of GVD -new optical modules, FADC readout units, underwater communications and trigger systems -have been developed, produced and tested in situ by long-term operating prototype strings in Lake Baikal. The prototyping phase of the GVD project has been started in April 2011 with the installation of a three string array (prototype cluster) which comprises all basic elements and systems of the GVD-telescope in Lake Baikal. We describe configuration and technical design of the GVD, present selected results obtained during 2008-2010 with prototype strings, and describe configuration and design of the 2011 prototype cluster.

a b s t r a c tWe review the status of high-energy acoustic neutrino detection activities in Lake Baikal. The Baikal collaboration constructed a hydro-acoustic device which may be regarded as a prototype subunit for a future underwater acoustic neutrino telescope. The device is capable of common operation with the Baikal neutrino telescope NT200+, and is operating at a depth of about 150 m on the ''NT200+ instrumentation string''. Our measurements show that the integral noise power in the frequency band 20-40 kHz can reach levels as low as about 1 mPa, i.e. one of the lowest noise levels measured at the currently considered acoustic neutrino sites. At the same time, short acoustic pulses with different amplitudes and shapes have been observed. Low sound absorption in Baikal freshwater and absence of strong acoustic noise sources do motivate further activities towards a large-scale acoustic neutrino detector in Lake Baikal.
