The report describes a 4-channel digital device which can be regarded as a
prototype elementary unit for future underwater acoustic neutrino telescopes.
Signals from the hydrophones, arranged in a pyramid-like geometry with 144 cm
spacing between the hydrophones, are amplified and processed by a 16-bit
ADC card with a frequency up to 200 kHz. There are three regimes of operation
of the instrument:
a) an autonomous analysis of acoustic background statistics;
b) online search for short acoustic pulses of definite shape, which can be
interpreted as signals from distant quasi-local sources;
c) transmission of a sample of data from all hydrophones to a shore computer
centre after a trigger signal from the Baikal Neutrino Telescope NT200+ has
been received.
In April 2006, the device was installed at a depth 100 m on a hydrophysical
mooring of NT200+ for long-term measurement. The data are presented and
discussed.
