Description
The sun could be a large axion emitter and thus an interesting object to study for axion searches. The International AXion Observatory (IAXO), as a next-generation axion helioscope, aims exactly for that purpose. The experiment will host a $20\,\text{m}$ long magnet with eight magnet bores and will be able to follow the sun for 12 hours per day. Each magnet bore will be equipped with a detector setup, most likely consisting of an X-ray optic followed by a low-background detector. IAXO aims for a sensitivity to the axion-photon coupling of $g_\text{aγ}$ around a $\text{few}\times 10^{12}\,\text{GeV}^{-1}$, exceeding the current limits at by the CAST experiment by more than an order of magnitude.
As an intermediate step and technology demonstrator, a smaller version of the experiment, called BabyIAXO, is currently being built at DESY in Hamburg (Germany). It will host a $10\,\text{m}$ long magnet with two bores of $70\,\text{cm}$ diameter each. Similar to IAXO, the experiment can track the sun for 12 hours per day, allowing advanced studies on all experiment subsystems while having at the same time physics potential beyond the current best limits for solar axions. Many components of the BabyIAXO experiment have already been produced; however, the superconducting magnet, as one of the major parts of the experiment, experienced some delays over the past years. This talk will present the current state of the BabyIAXO and IAXO experiment and an overview on the aimed physics searches.
