Precision self-monitoring calibration module for the IceCube Upgrade — •Tobias Pertl and Felix Henningsen — Technische Universität München

The IceCube detector is a large-volume neutrino detector embedded in the Antarctic ice at the geographic South Pole. As the detector has been online for over a decade, advancements in hardware and an increased scientific focus on oscillation and high-energy physics as well as re-calibration of the detector have driven the IceCube Upgrade. This upgrade encompasses a detector expansion with seven new densely instrumented strings focussed on low-energy physics. A novel type of precision optical calibration module -- or POCAM -- for large-volume detectors has been developed and will be deployed throughout the instrumented volume of the IceCube Upgrade. We report on the design and extended performance of the POCAM instrument as well as calibration procedures.
