  1. CAST: The CERN Axion Solar Telescope and tofinish... THE AXION anintruder in the neutrino school Iñaki Ortega ISAPP 2013 LSC, Canfranc

  2. Proposedtosolvethecalled “Strong CP problem” New pseudo-scalarfield. FirstproposedbyPeccei and Quinn. ParticleinterpretationbyWeinberg and Wilczek Someproperties of theaxion: -Practicallystable - Verylowmass What are axions? islike a ghost!! - Verylowcross-section Solutionto CP problemandcandidatetoDarkMatter Axioncouplestophoton: Primakoffeffect

  3. Optimizedmagnet: • figure of merit ~300 bigger • than CAST • Lowbackgrounddetectors: • bigexperiencefrom CAST Thefuturehelioscope IAXO The International AXionObservatory - X rayoptics: greatimprovement of signaltonoise ratio
