The ANTARES Cherenkov Neutrino Telescope
ANTARES is a European research collaboration which has constructed a neutrino telescope in the deep Mediterranean Sea off the coast of southern France.
In its currently final setup, which has been completed in May 2008, the telescope consists of 12 vertical strings and an instrumentation line that are anchored to the seabed and tightened by underwater buoys. All 12+1 lines are taking data successfully. Each of the 12 telescope strings is composed of 25 floors with 3 optical modules each and a total length of about 460 m. The detector instruments a total water volume of about 0.01 km3.
The reconstruction of neutrinos is achieved indirectly with the help of Cherenkov light, which is emitted by charged particles like electrons or muons that are created in interactions of neutrinos with nuclei in the water molecules.
Some of the physics goals of ANTARES are the measurement of the diffuse cosmic neutrino flux, the precise measurement of the angular and energy spectrum of the neutrinos, the search for cosmic point sources and the search for signals of WIMPS and other exotic particles.
The Erlangen ANTARES group
The ANTARES group at ECAP is a collaboration member since November 2001. Our group participates in the development of efficient neutrino reconstruction techniques and studies the atmospheric muon background. Additionally, we are involved in various aspects of detector calibration and develop data based methods to determine the absolute detector positioning which is essential to achieve high resolution track reconstruction. Another focus of our work is set on the development and investigation of acoustic neutrino detection methods for a larger future detector design.
