Simulation Studies for Characterization of a Calibration Device for the IceCube Upgrade — •Selina Rudolph for the IceCube collaboration — Technical University of Munich (TUM)

The IceCube neutrino observatory at the geographic South Pole has officially begun its Upgrade campaign after successfully operating for over ten years. In addition to the existing 86 strings instrumented with over 5,000 photosensors, the IceCube Collaboration will deploy seven new strings. The Upgrade focuses on improving the lower-energy regime and sensitivity to neutrino oscillation parameters, as well as enhancing the recalibration of the gigaton glacial ice detector medium. One of the instruments deployed in the campaign is the Precision Optical Calibration Module (POCAM), which was developed and assembled at Technical University of Munich (TUM). Over 20 next-generation POCAMs will be utilized to further reduce existing detector systematics. This talk provides an overview of the simulation efforts, specifically for a series of special operations carried out during the installation. These Monte Carlo simulation studies are conducted to predict the POCAM's ability to characterize certain ice parameters, which are crucial for calibration and analysis studies.
