摘要：The CERN Axion Solar Telescope (CAST) is searching for axions produced in the Sun's core
by the Primakoff process. CAST is using a decommissioned Large Hadron Collider (LHC) test
magnet where axions could be converted back into X-rays with energies up to 10 keV. Analysis of
the 2003 data showed no signal above background implying an upper limit for the axion-photon
coupling constant gagg < 1.16 1010 GeV1 at 95% C.L. for ma . 0.02 eV [1]. The higher
quality 2004 data is presently under analysis. CAST Phase II is scheduled to start in late 2005.
This will be the rst step in extending CAST's sensitivity to axion rest masses up to 1 eV.
