Search for a Dark-Matter-Induced Cosmic Axion Background with ADMX
/ ADMX Collaboration
We report the first result of a direct search for a Cosmic ${\it axion}$ Background (C$a$B) - a relativistic background of axions that is not dark matter - performed with the axion haloscope, the Axion Dark Matter eXperiment (ADMX). Conventional haloscope analyses search for a signal with a narrow bandwidth, as predicted for dark matter, whereas the C$a$B will be broad. [...]

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 . [...]

Future axion searches with the International Axion Observatory (IAXO)

U.) ; Dael, A (IRFU, Saclay) ; Dafni, T (Zaragoza U.) ; Davenport, M (CERN) et al.
The International Axion Observatory (IAXO) is a new generation axion helioscope aiming at a sensitivity to the axion-photon coupling of gaγ few × 10−12 GeV−1, i.e. 1–1.5 orders of magnitude beyond the one achieved by CAST, currently the most sensitive axion helioscope. [...]

The International Axion Observatory (IAXO) will be a forth generation axion helioscope. As its primary physics goal, IAXO will look for axions or axion-like particles (ALPs) originating in the Sun via the Primakoff conversion of the solar plasma photons. [...]
