Photomultiplier simulation in COMSOL Multiphysics — •Willem Achtermann, Alexander Kappes, and Markus Dittmer for the IceCube collaboration — Institut für Kernphysik, Westfälische Wilhelms-Universität Münster, Münster, Germany

Photomultiplier tubes (PMTs) are used in water Cherenkov neutrino detectors such as IceCube and KM3NeT. They play a central role in the performance of the detector and therefore a deep understanding of their properties is crucial for the operation and improvement of the experiment. In this talk, I discuss some of the timing parameters, e.g., the transit time (spread) for a PMT, which I investigate using a COMSOL multiphysics simulation. The current state of simulation will be shown and some insights into the working principle of PMTs and simulation results will be given.
