New Upper Limit on the Axion-Photon Coupling with an Extended CAST Run with a Xe-Based Micromegas Detector / CAST Collaboration
Hypothetical axions provide a compelling explanation for dark matter and could be emitted from the hot solar interior. The CERN Axion Solar Telescope (CAST) has been searching for solar axions via their back conversion to X-ray photons in a 9-T 10-m long magnet directed towards the Sun. [...]

An update on the Axion Helioscopes front: current activities at CAST and the IAXO project / Dafni, T (Zaragoza U.) ; Arik, M (Dogus U., Kadikoy) ; Armengaud, E (IRFU, SPhN, Saclay) ; Aune, S (IRFU, Saclay) ; Avignone, F T (South Carolina U.) ; Barth, K (CERN) ; Belov, A (Moscow, INR) ; Betz, M (CERN) ; Bräuninger, H (Garching, Max Planck Inst., MPE) ; Brax, P (CERN) et al.
Although they have not yet been detected, axions and axion-like particles (ALPs) continue to maintain the interest (even increasingly so) of the rare-event searches community as viable candidates for the Dark Matter of the Universe but also as a solution for several other puzzles of astrophysics. Their property of coupling to photons has inspired different experimental methods for their detection, one of which is the helioscope technique. [...]

The IAXO Helioscope / Ferrer Ribas, E. (IRFU, Saclay) ; Armengaud, E. (IRFU, Saclay) ; Avignone, F.T. (South Carolina U.) ; Betz, M. (CERN) ; Brax, P. (IPhT, Saclay) ; Brun, P. (IRFU, Saclay) ; Cantatore, G. (INFN, Trieste ; Trieste U.) ; Carmona, J.M. (Zaragoza U.) ; Carosi, G.P. (LLNL, Livermore) ; Caspers, F. (CERN) et al.
The IAXO (International Axion Experiment) is a fourth generation helioscope with a sensitivity, in terms of detectable signal counts, at least 10(4) better than CAST phase-I, resulting in sensitivity on g(a)(γ) one order of magnitude better. To achieve this performance IAXO will count on a 8-coil toroidal magnet with 60 cm diameter bores and equipped with X-ray focusing optics into 0.20 cm(2) spots coupled to ultra-low background Micromegas X-ray detectors.

The Next Generation of Axion Helioscopes: The International Axion Observatory (IAXO) / Vogel, J K (LLNL, Livermore) ; Armengaud, E (IRFU, Saclay) ; Avignone, F T (South Carolina U.) ; Betz, M (CERN) ; Brax, P (IRFU, Saclay) ; Brun, P (IRFU, Saclay) ; Cantatore, G (INFN, Trieste ; Trieste U.) ; Carmona, J M (Zaragoza U.) ; Carosi, G P (LLNL, Livermore) ; Caspers, F (CERN) et al.
The International Axion Observatory (IAXO) is a proposed 4 th -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. IAXO will achieve a sensitivity to the axion-photon coupling g aγ down to a few ×10 −12 GeV −1 for a wide range of axion masses up to ∼ 0 . [...]

A Micromegas-based low-background x-ray detector coupled to a slumped-glass telescope for axion research / Aznar, F. (Zaragoza U.) ; Castel, J. (Zaragoza U.) ; Christensen, F.E. (Denmark, Tech. U.) ; Dafni, T. (Zaragoza U.) ; Decker, T.A. (LLNL, Livermore) ; Ferrer-Ribas, E. (IRFU, Saclay) ; Garcia, J.A. (Zaragoza U.) ; Giomataris, I. (IRFU, Saclay) ; Gracia, J.G. (Zaragoza U.) ; Hailey, C.J. (Columbia U.) et al.
We report on the design, construction and operation of a low background x-ray detection line composed of a shielded Micromegas (micromesh gaseous structure) detector of the microbulk technique. The detector is made from radiopure materials and is placed at the focal point of a $\sim$~5 cm diameter, 1.3 m focal-length, cone-approximation Wolter I x-ray telescope (XRT) comprised of thermally-formed (or "slumped") glass substrates deposited with multilayer coatings.

Solar axions could be converted into x-rays inside the strong magnetic field of an axion helioscope, triggering the detection of this elusive particle. Low background x-ray detectors are an essential component for the sensitivity of these searches. [...]
