Simulation of Light Propagation Through Hole Ice for the IceCube Experiment — •Sebastian Fiedlschuster for the IceCube collaboration — Friedrich-Alexander-Universität Erlangen-Nürnberg, ECAP, Erwin-Rommel-Str. 1, 91058 Erlangen

IceCube is a neutrino observatory at Earth’s South Pole that uses glacial ice as detector medium where particles from neutrino interactions produce Cherenkov light as they move through the ice, which then is detected by an array of photo detectors deployed within the ice. Hole ice is the refrozen water in the drill holes that were needed to deploy the detector modules.

Aiming to improve the detector calibration for the current IceCube detector as well as for the upcoming upgrade, a new method to simulate the propagation of light through the hole ice has been introduced. The new method allows a ray-tracing simulation of light through ice volumes of different optical properties, such as one or several hole-ice cylinders with specific positions, sizes, scattering lengths and absorption lengths. The effect of shadowing cables can be studied by modeling cables as opaque volumes. This talk will outline the simulation method and present current results.
