Validation Tests of 10,200 Photomultiplier Tubes for the IceCube Upgrade — •Tara Haji Azim, Philipp Behrens, Erik Büchau, Lasse Halve, Joëlle Savelberg, Lars Schmidt, and Christopher Wiebusch for the IceCube collaboration — III. Physikalisches Institut B, RWTH Aachen University

The Upgrade of the IceCube Neutrino Observatory incorporates the installation of Photomultiplier Tubes (PMTs) as parts of advanced multi-PMT Digital Optical Modules (mDOMs). For this purpose, 10,200 of 3-inch PMTs were quality controlled prior to the commissioning phase at two facility sites, one at RWTH Aachen University and the other one at TU Dortmund University. All PMTs have undergone extensive acceptance tests including single-photon response, detection efficiency, time-resolution, background rates, high-voltage dependence, and more. In this talk, we will review selected results of the survey.
