New solar axion search using the CERN Axion Solar Telescope with He4 filling 2015 Access copy available to the general public Unrestricted The CERN Axion Solar Telescope (CAST) searches for a --> conversion in the 9 T magnetic field of a refurbished LHC test magnet that can be directed toward the Sun. Two parallel magnet bores can be filled with helium of adjustable pressure to match the x-ray refractive mass m-a to the axion search mass ma. After the vacuum phase (2003–2004), which is optimal for ma <0.02 eV, we used 4He in 2005–2007 to cover the mass range of 0.02–0.39 eV and 3He in 2009–2011 to scan from 0.39 to 1.17 eV. After improving thedetectors and shielding, we returned to 4He in 2012 to investigate a narrow ma range around 0.2 eV (“candidate setting” of our earlier search) and 0.39–0.42 eV, the upper axion mass range reachable with 4He, to “cross the axion line” for the KSVZ model. We have improved the limit on the axion-photon coupling... info:eu-repo/grantAgreement/EUR/EIC-CERN-2011-0006 info:eu-repo/grantAgreement/EC/FP7/240054/EU/Novel Developments in Time Projection Chambers (TPCs) for Rare Event Searches in Underground Astroparticle EXperiments/TREX info:eu-repo/grantAgreement/ES/MINECO-FEDER/FPA2008-03456 info:eu-repo/grantAgreement/ES/MINECO-FEDER/FPA2011-24058 info:eu-repo/semantics/openAccess by-nc-sa http://creativecommons.org/licenses/by-nc-sa/3.0/es/ info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Aune, S.
