Description
KM3NeT (km3 Neutrino Telescope) is planned to be a deep-sea multidisciplinary observatory in the Mediterranean Sea that will provide innovative science opportunities spanning Astroparticle Physics and Earth and Sea Science. KM3NeT will consist of several hundreds of vertical structures, which carry photo-sensors and devices for calibration and environmental measurements. The photo-sensor unit is a digital optical module (DOM) consisting of a 17-inch diameter pressure resistant glass sphere housing 31 3-inch photomultiplier (PMT) tubes. The front-end electronics is based on the use of the time over threshold (ToT) as the main signal processing technique.
The track reconstruction techniques applied to the KM3NeT data uses the arrival times of the first photon on each PMT and the deposited charge. We report on the performance of the ToT technique in reconstructing the PMT signal characteristics, in particular the first photon arrival time and the charge deposited on the PMT. For this study, we have used simulated data generated with the HOURS (HOU Reconstruction & Simulation) software package.
