IceCube Systematic Errors Investigation: Simulation of the Ice — Elisa Resconi¹, Anne Schukraft², and •Martin Wolf¹ — ¹Max Planck Institute for Nuclear Physics, Heidelberg, Germany — ²RWTH Aachen University, Germany

IceCube is a neutrino observatory for astroparticle and astronomy research at the South Pole. It uses one cubic kilometer of Antartica's deepest ice (1500m-2500m in depth) to detect Cherenkov light, generated by charged particles traveling through the ice, with an array of phototubes encapsulated in glass pressure spheres. The arrival time as well as the charge deposited of the detected photons represent the base measurements that are used for track and energy reconstruction of those charged particles. The optical properties of the deep antarctic ice vary from layer to layer. Measurements of the ice properties and their correct modeling in Monte Carlo simulation is then of primary importance for the correct understanding of the IceCube telescope behavior.

After a short summary about the different methods to investigate the ice properties and to calibrate the detector, we will show how the simulation obtained by using this information compares to the measured data and how systematic errors due to uncertain ice properties are determined in IceCube.
