Event reconstruction for different detector geometries in a toy simulation of water-Cherenkov neutrino telescopes — •Franziska Kirchner for the IceCube collaboration — Erlangen Centre for Astroparticle Physics (ECAP), Friedrich-Alexander-Universität Erlangen-Nürnberg

Water-Cherenkov neutrino detectors are typically built with instrumentation strings placed on a triangular grid. Next-generation detectors such as P-ONE or IceCube-Gen2 are planned as less ordered structures so that no charged particle can pass through the detector without approaching any detector string. However, it is not fully understood which detector geometries result in an optimal resolution of event energies and event positions. The talk will present a toy simulation of various detector geometries and corresponding cascade and muon track event reconstructions, which is used to investigate the corresponding resolutions.
