Muon Track Reconstruction in the Outer Detector of Borexino — •Michael Wurm, Franz von Feilitzsch, Marianne Göger-Neff, Timo Lewke, Quirin Meindl, Lothar Oberauer, and Jürgen Winter for the BOREXINO collaboration — Technische Universität München, Physik-Dpt. E15

The Borexino Detector is designed for the detection of low-energetic solar neutrinos. Cosmic muons and their spallation products are an important background for these measurements.
The Inner Detector of the experiment containing the liquid-scintillator target is surrounded by an additional Water Cherenkov Detector. This Outer Detector can be used to reconstruct the tracks of cosmic muons that are crossing both Inner and Outer Detector. The approach of the reconstruction, estimates of the systematic uncertainties and its impact on data analysis will be discussed.
