LNGS: F. AVIGNONE - THE HISTORY AND FUTURE OF SEARCHES FOR AXIONS FROM THE SUN
LABORATORI NAZIONALI DEL GRAN SASSO
From the introduction of the axion in the 1970s as a result of the Peccei-Quinn proposed solution to the strong CP Problem, to the present, there have been many experimental efforts to search for this Goldstone boson. The first search for solar axions was performed with a low-background germanium detector in the Homestake Goldmine in the 1980s. Very recent experiments done by the EDELWEISS and Majorana Collaborations used germanium detectors to search for solar axions generated by the bremsstrahlung and Compton processes. In 1983, Pierre Sikivie introduced the concept of the magnetic helioscope that employs the Primakoff process to convert axions to photons in a strong transverse magnetic field. Several experiments were launched using this technique, concluding with the present CERN Axion Solar Telescope (CAST). A new proposed helioscope, the International Axion Observatory (IAXO), will be discussed. IAXO is designed to extend the sensitivity well beyond that achieved by CAST. ----------------- Frank Avignone University of South Carolina USA
