| Abstract | The AMADEUS system described in this article is integrated i nto the ANTARES neutrino telescope in the Mediterranean Sea and aims at the inve st gation of techniques for acoustic detection of neutrinos in the deep sea. Installed a t water depths between 2000 and 2400 m, its acoustic sensors employ piezo-electric elem ents for the broad-band recording of signals with frequencies ranging up to 125 kHz with typ ical sensitivities around −145 dB re. 1V/ μPa (including preamplifier). Completed in May 2008, AMADEUS consists of six “acoustic clusters”, each comprising six acous tic sensors that are arranged at distances of roughly 1 m from each other. Three acoustic clus ters each are installed along two vertical mechanical structures (so-called lines) of th e ANTARES detector at a horizontal distance of 240 m. Vertical spacings within a line range f rom 15 m to 125 m. Each cluster contains custom-designed electronics boards to amplify an d digitise the acoustic data from the sensors. The data transmission to shore is done via optic al fibres, using the TCP/IP protocol. An on-shore computer cluster, currently consisting of four dedicated servers, is used to process, filter and store the selected data. The daily volu me of recorded data is about 10 – 20 GByte. The system is operating continuously and automat ically, requiring only little human intervention. AMADEUS allows for extensive studies o f b th transient signals and ambient noise in the deep sea as well as signal correlations o n several length scales and localisation of acoustic point sources. Thus the system is e xcellently suited to assess the background conditions that affect the measurement of bipol ar pulses expected to originate from neutrino interactions. This in turn allows for feasibi lity studies of a future large-scale acoustic neutrino telescope in the Mediterranean Sea. |
