An accurate solar axions ray-tracing response of BabyIAXO 2025 Access copy available to the general public Unrestricted BabyIAXO is the intermediate stage of the International Axion Observatory (IAXO) to be hosted at DESY. Its primary goal is the detection of solar axions following the axion helioscope technique. Axions are converted into photons in a large magnet that is pointing to the sun. The resulting X-rays are focused by appropriate X-ray optics and detected by sensitive low-background detectors placed at the focal spot. The aim of this article is to provide an accurate quantitative description of the different components (such as the magnet, optics, and X-ray detectors) involved in the detection of axions. Our efforts have focused on developing robust and integrated software tools to model these helioscope components, enabling future assessments of modifications or upgrades to any part of the IAXO axion helioscope and evaluating the potential impact on the experiment’s sensitivity. In this manuscript, we demonstrate the application of these tools by presenting a precise signal calculation and response analysis of BabyIAXO’s sensitivity to the axion-photon coupling. Though focusing on the Primakoff solar flux component, our virtual helioscope model can be used to test different production mechanisms, allowing for direct comparisons within a unified framework. info:eu-repo/grantAgreement/ES/DGA/E16-23R info:eu-repo/grantAgreement/ES/DGA/E21-23R info:eu-repo/grantAgreement/ES/DGA/E27-23R info:eu-repo/grantAgreement/EC/H2020/788781/EU/Towards the detection of the axion with the International Axion Observatory/IAXOplus This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 788781-IAXOplus info:eu-repo/grantAgreement/EC/H2020/802836/EU/Axions and relatives across different mass scales/AxScale This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 802836-AxScale info:eu-repo/grantAgreement/ES/MICINN/PID2019-108122GB-C31 info:eu-repo/grantAgreement/ES/MICINN/PID2022-137268NB-C51 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Altenmüller, K.
