Conceptual design of BabyIAXO, the intermediate stage towards the International Axion Observatory 2021 Access copy available to the general public Unrestricted This article describes BabyIAXO, an intermediate experimental stage of the International Axion Observatory (IAXO), proposed to be sited at DESY. IAXO is a large-scale axion helioscope that will look for axions and axion-like particles (ALPs), produced in the Sun, with unprecedented sensitivity. BabyIAXO is conceived to test all IAXO subsystems (magnet, optics and detectors) at a relevant scale for the final system and thus serve as prototype for IAXO, but at the same time as a fully-fledged helioscope with relevant physics reach itself, and with potential for discovery. The BabyIAXO magnet will feature two 10 m long, 70 cm diameter bores, and will host two detection lines (optics and detector) of dimensions similar to the final ones foreseen for IAXO. BabyIAXO will detect or reject solar axions or ALPs with axion-photon couplings down to ga¿ ~ 1.5 × 10-11 GeV-1, and masses up to ma ~ 0.25 eV. BabyIAXO will offer additional opportunities for axion research in view of IAXO, like the development of precision x-ray detectors to identify particular spectral features in the solar axion spectrum, and the implementation of radiofrequency-cavity-based axion dark matter setups. info:eu-repo/grantAgreement/ES/AEI/CEX2019-000918-M 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/MINECO-FEDER/FPA2016-76978-C3-1-P info:eu-repo/grantAgreement/ES/MINECO/PID2019-108122GB-C31 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 6.376 2021 PHYSICS, PARTICLES & FIELDS 6 / 29 = 0.207 2021 Q1 T1 0.895 2021 Nuclear and High Energy Physics 2021 Q2 10.3 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Altenmüller, K.
