BabyIAXO: prospects and status of a new generation axion helioscope — •Daniel Heuchel1 and the IAXO-Collaboration2 — 1Deutsches Elektronen-Synchrotron (DESY) — 2https://iaxo.desy.de
In order to search for solar axions and axion-like particles (ALPs) with unprecedented sensitivities, the International Axion Observatory (IAXO) aims to convert those particles via the interaction with virtual photons into X-rays in a strong magnet pointing towards the sun followed by high-precision focusing and ultra-low background and high-efficiency X-ray detectors.
The intermediate experimental stage, BabyIAXO, proposed to be sited at DESY Hamburg, will not only serve as a prototype-stage for all IAXO subsystems, but it will be a fully fledged helioscope with potential for discovery. Along with a 10 m long and about 2 T strong superconducting magnet hosting two 70 cm diameter bores, optics and detector systems very similar to the ones foreseen for IAXO will complete the two detection lines. Based on this setup, BabyIAXO will be able probe axion-photon couplings down to 1.5× 10−11 GeV−1 for axion masses of up to 0.25 eV.
In this contribution, the general prospects of BabyIAXO, the current status of the different BabyIAXO subsystems including the different X-ray detector technologies and the ongoing background simulation campaigns are presented and discussed.
