Abstract The BGOOD experiment at the ELSA facility is designed to investigate the hadron structure through the study of non-strange and strange meson photoproduction on the nucleon. The experimental setup combines a BGO crystal calorimeter with a large-aperture forward magnetic spectrometer, providing excellent detection capabilities for both neutral and charged particles. To ensure accurate final-state reconstruction and minimize particle misidentification, photon-neutron discrimination in the BGO calorimeter plays a crucial role. The different physical processes governing the interaction of high-energy photons and neutrons with the BGO give rise to distinct cluster features in the detector. In this contribution, the criteria developed for photon-neutron discrimination are presented and discussed, together with a comparison to Geant4-based simulations.
