| Résumé : | The ANTARES collaboration is deploying an underwater neutrino telescope in the Mediterranean Sea which consists of a tridimensional matrix of photomultipliers (PMTs). Muon neutrinos will be detected through the Cherenkov light induced by the muon produced in the neutrino interaction with matter. The muon track will be reconstructed using the available information given by the number of photons and their different arrival times at the PMTs. Other types of neutrino events will also be detected. Calibration is a key issue in the reconstruction of the muon tracks, therefore different calibration systems will be employed in the ANTARES telescope. In order to achieve the best possible pointing resolution for astronomy, an accuracy of δ∼ 0.5 ns in the relative time calibration among PMTs is desirable. Before the deployment of the strings this calibration is performed in a dedicated dark-room. Once in the sea, it will be achieved using an echo-based clock calibration system and pulses of light emitted by LEDs within the Optical Modules and Optical Beacons distributed along the strings. On the other hand, an absolute time calibration of around 1 ms will be sufficient for the correlation with all the interesting astrophysical sources. |
