Simulation studies on the thermal properties of the mDOM for the IceCube Upgrade — •Judith Schneider, Gisela Anton, Jonas Reubelt, and Gerrit Wrede for the IceCube collaboration — Erlangen Centre for Astroparticle Physics, 91058 Erlangen, Germany

In the framework of a planned upgrade of the IceCube Neutrino Observatory and a next-generation neutrino telescope at the South Pole, new optical modules are being developed, which are expected to significantly increase the detector sensitivity. One of such concepts is the multi-PMT Digital Optical Module (mDOM) which features 24 three-inch PMTs inside a pressure vessel resulting in a homogeneous directional sensitivity. We have implemented the construction of a mDOM with its substantial components and their thermal properties in a COMSOL simulation as well as a heat source reproducing the expected heat input of the mDOM electronics. With the assumption that all heat is conducted away via the pressure vessel, the thermal flux is determined. The results are compared to measurements of the thermal behavior of a mDOM in the climate chamber.
