Geometry calibration of the KM3NeT neutrino telescope using atmospheric muons — •Daniel Guderian and Alexander Kappes — Institut für Kernphysik, Westfälische-Wilhelms-Universität, Münster

The KM3NeT neutrino telescope consists of a network of large volume Cherenkov detectors at the bottom of the Mediterranean Sea destined to look for neutrino interactions in the water. With its two different sites, ORCA and ARCA, currently under construction, specializing in lower and higher neutrino energies, respectively, it aims at studying physics spanning from the determination of the neutrino mass hierarchy to detection of neutrinos from astrophysical objects. With the ongoing deployment of sensors, calibration becomes a highly important task to perform in order to provide the precision necessary for data analysis.

In this talk studies on a method using atmospheric muons for calibration are presented in which the reconstructed muon tracks are used to evaluate the detector geometry. In particular, position and time offset determinations of the photosensors can be achieved applying this technique.
