Description

The KM3 Neutrino Telescope (KM3NeT) will be a deep-sea multidisciplinary observatory in the Mediterranean Sea. The accurate knowledge of the optical properties of the sea water is very important for the performance evaluation of the telescope. In this work we describe a technique for the evaluation of the parameters describing the scattering characteristics of the sea water using one Multi-PMT Optical Module that detects scattered optical photons which are emitted from a laser. For each photomultiplier, we compare the number of the detected photons and their arrival time profile with expectations corresponding to certain values of the scattering parameters. This comparison can provide an accurate estimation of the optical scattering properties of the sea water. For this study the expectations (i.e. the number of photons observed in each photomultiplier and their time distribution) are estimated using the full photon tracking mode of the HOURS (Hellenic Open University Reconstruction & Simulation) software package.
