Abstract

The CERN Axion Solar Telescope (CAST) searches for a→γ 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 mγ to the axion search mass ma. After the vacuum phase (2003-2004), which is optimal for ma0.02eV, we used He4 in 2005-2007 to cover the mass range of 0.02-0.39 eV and He3 in 2009-2011 to scan from 0.39 to 1.17 eV. After improving the detectors and shielding, we returned to He4 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 He4, to "cross the axion line" for the KSVZ model. We have improved the limit on the axion-photon coupling to gaγ<1.47×10-10GeV-1 (95% C.L.), depending on the pressure settings. Since 2013, we have returned to the vacuum and aim for a significant increase in sensitivity.
