Testing the Precision Optical Calibration Module for PINGU — Martin Jurkovic and •Kilian Holzapfel for the IceCube collaboration — TU München, Physik-Department, Excellence Cluster Universe, Boltzmannstr. 2, 85748 Garching

The Precision IceCube Next Generation Upgrade (PINGU) is primarily designed to determine the neutrino mass hierarchy. This measurement requires an accurate calibration of the detector in order to reduce systematic uncertainties. The Precision Optical Calibration Modules (POCAM) will be placed in the detector as a well calibrated artificial light source in the ice. The POCAM will be enclosed in a glass sphere identical to those used for the detector modules. To construct and simulate a prototype of the POCAM, every component needs to be analyzed by their optical characteristics and by the behavior in temperatures down to -50°C. Therefore a highly shielded an isolated environment has to be build up. We report the status of the testing environment and the hardware selected.
