Description
The ANTARES telescope is a device of a 0.1 km size to detect high energy
neutrinos. It is located in the Mediterranean Sea at a depth of 2500 meters.
It consists of a three-dimensional matrix of optical modules (OM) containing
photomultiplier tubes. As of September 2006 two complete lines and an
instrumentation line, called MILOM, are deployed and fully operational for
data taking. Three additional lines will be connected by the end of February
2007 allowing the first up-going muon track reconstruction. At the end of
2007, the full Antares telescope will be operational with twelve lines. All
technical aspects are under control from the mechanical architecture to the
constant improvement of the all-data-to-shore concept. This talk will focus
on the photon signal processing that allows the neutrino track
reconstruction. After a first review of the line architecture, we will present
the signal processing and transport from the OM detector to the on-shore
storage. During the R&D phases, the ANTARES collaboration has developed
new concepts in terms of detector integration, front-end electronics
architecture, cables, DAQ hardware architecture and software management.
Finally, preliminary results of the performances of the detector will be
shown.
