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 gaγγ < 1.16 × 10−10 GeV−1 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 first step in extending CAST’s sensitivity to axion rest masses up to ∼ 1 eV.
