Automation of the PMT Acceptance Tests for the IceCube Upgrade mDOMs — •Lasse Halve¹, Hannah Erpenbeck¹, Maja Freienhofer², Konstantin Mrozik², Joëlle Savelberg¹, Johannes Werthebach², and Christopher Wiebusch¹ for the IceCube collaboration — ¹RWTH Aachen University - Physics Institute III B, Aachen, Germany — ²Astroparticle Physics WG Rhode, TU Dortmund University, Germany

The IceCube Upgrade will extend the IceCube Neutrino observatory with seven additional cable-strings of instrumentation. More than 400 multiple-PMT Digital Optical Modules (mDOMs), with 24 3'' Photomultiplier Tubes (PMTs) each, will be deployed. We are testing more than 10.000 PMTs for compliance with manufacturer specifications before the integration into the final modules. A dedicated software for steering the test facilities at RWTH Aachen University and TU Dortmund University for a fully automated operation and online analysis has been developed. We present the design principles and specific solutions for full automization of the test procedures and analyses of PMT data.
