First results from simulations of an IceCube-Gen2 high-energy detector equipped with multi-PMT optical modules — •Thomas Kittler and Alexander Kappes for the IceCube collaboration — Erlangen Centre for Astroparticle Physics, Erlangen, Germany

The high energy array (HEA) of IceCube-Gen2, the planned next generation neutrino telescope at the South Pole, aims at the detection of neutrinos with Eν > 100 TeV. In the current baseline design which follows the proven IceCube design, the central detection unit, called Digital Optical Module (DOM), is a pressure resistant glass sphere equipped with a single 10Nodq photomultiplier (PMT) facing downwards. In parallel, alternative designs are under development which aim at improving on several aspects of the baseline design. One such design is the multi-PMT optical module (mDOM) which incorporates 24 3Nodq PMTs uniformly distributed within the sphere. Apart from a larger photocathode area, this design features a very uniform solid-angle coverage and intrinsic directional sensitivity. The talk presents first results from simulations of a HEA detector equipped with mDOMs including studies concerning their intrinsic directional sensitivity.
