Production, Installation & Detector Operations of a Calibration Device for the IceCube Upgrade — •Leonhard Eidenschink, Andrii Terliuk, and Patrick Schaile for the IceCube collaboration — Technical University of Munich

The Precision Optical Calibration Module (POCAM) is an isotropic, multi-wavelength, self-monitoring optical calibration device. The IceCube Upgrade, an extension of the IceCube detector located at the geographic South Pole, includes seven new strings equipped with more than 700 modules, 22 of which are POCAM devices. All produced POCAMs underwent extensive calibration of their optical properties at our testing facility at Technical University of Munich (TUM). The purpose of POCAM is to emit a well-characterized isotropic light pulse that allows for calibration of both the optical medium and the detector modules. In addition to the routine calibration operations planned after full deployment, a series of special operations were carried out during the installation. This talk provides an overview of the device production, installation in the IceCube Upgrade, and the special calibration operations performed, along with their first data.
