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 cm2 spots coupled to ultra-low background Micromegas X-ray detectors. The magnet will be on a platform that will allow solar tracking for 12 hours per day. The next short term objectives are to prepare a Technical Design Report and to construct the first prototypes of the hardware main ingredients: demonstration coil, X-ray optics and low background detector while refining the physics case and studying the feasibility studies for Dark Matter axions.2015http://zaguan.unizar.es/record/5774010.1088/1742-6596/650/1/012009http://zaguan.unizar.es/record/57740oai:zaguan.unizar.es:57740info:eu-repo/grantAgreement/EC/FP7/240054/EU/Novel Developments in Time Projection Chambers (TPCs) for Rare Event Searches in Underground Astroparticle EXperiments/TREXinfo:eu-repo/grantAgreement/ES/MICINN/CPAN-CSD2007-00042info:eu-repo/grantAgreement/ES/MINECO-FEDER/FPA2008-03456info:eu-repo/grantAgreement/ES/MINECO-FEDER/FPA2011-24058Journal of Physics: Conference Series 650 (2015), 012009 [8 pp.]byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
