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 g_(a gamma) < 1.16 × 10^(-10) GeV^(-1) at 95% C.L. for m_a < = 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.
