TL;DR: The International Axion Observatory (IAXO) as mentioned in this paper is the most powerful axion helioscope, reaching sensitivity to axion-photon couplings down to a few × 10−12 GeV−1 and thus probing a large fraction of the currently unexplored axion and ALP parameter space.

TL;DR: The International Axion Observatory (IAXO) as mentioned in this paper is a proposed 4th generation axion helioscope with a purpose-built 8-coils toroidal superconducting magnet.

TL;DR: The International Axion Observatory (IAXO) as discussed by the authors is a next generation axion helioscope aiming at a sensitivity to the axion-photon coupling of a few 10−12−1 GeV−1, i.e. 1-1.5 orders of magnitude beyond sensitivities achieved by the currently most sensitive axion solar telescope, the CERN Axion Solar Telescope (CAST).

TL;DR: The International Axion Observatory (IAXO) as discussed by the authors is the most powerful axion helioscope to date in terms of signal-to-noise ratio, reaching sensitivity to axion-photon couplings down to a few times 10 − 12 − 1 − 2 GeV$ − 1 /ε − 1/ε 2 ) and thus probing a large fraction of the currently unexplored axion and ALP parameter space.

TL;DR: The International Axion Observatory (IAXO) as discussed by the authors is a proposed 4th-generation axion helioscope with the primary physics research goal to search for solar axions via their Primakoff conversion into photons of 1 - 10 keV energies in a strong magnetic field.
