Production of the Precision Optical Calibration Module (POCAM) — •Patrick Schaile, Leonhard Eidenschink, and Andrii Terliuk — Technical University of Munich, TUM School of Natural Sciences, Department of Physics, James-Franck-Straße 1, D-85748 Garching bei München, Germany

In the context of the IceCube Upgrade, which mainly aims to improve and extend the scientific capabilities of the IceCube Neutrino Observatory, a Precision Optical Calibration Module, the POCAM, has been developed. It is an isotropic, self-monitoring calibration light source, which will be deployed into the Antarctic ice as a new part of the detector and is meant to investigate and determine the optical detector systematics to high precision. The improved knowledge on parameters like absorption or scattering length will eventually lead to likewise improved detector sensitivity and data analyses. Currently the project is in the production and calibration stage, in which the necessary parts of the devices are either produced or combined respectively to its required functional units which are eventually tested and calibrated. In total there will be 21 POCAMs used in IceCube, while the first devices will be ready for deployment in 2024.
