Tracking in large volume liquid scintillator and water cherenkov detectors applied to LENA — •Björn Wonsak — Universität Hamburg

Large volume liquid scintillator and water cherenkov detectors are widely used in neutrino physics. Both detector types allow for measuring the energy deposition and give some (limited) information on the event type. A topological analysis, as in fine grained detectors, was not possible up to now.

A new reconstruction method aiming to provide this ability, which is based on the propagation time of the detected light, is presented. The method is under development. Currently, a spatial resolution of less than 20 cm is reached for single tracks and the energy deposit per track segment seems to be accessible. The aim is to achieve a resolution of a few centimeters and to make the method applicable for complex topologies. In the long run we strive for some capabilities to separate electron induced electromagnetic showers from pion induced ones, the later beeing a major background for neutrino oscillation experiments with long baseline beams.
