    "abstract": "A low background Micromegas detector has been operating on the CAST\nexperiment at CERN for the search of solar axions during the first phase of the\nexperiment (2002-2004). The detector operated efficiently and achieved a very\nlow level of background rejection ($5\\times 10^{-5}$ counts\nkeV$^{-1}$cm$^{-2}$s$^{-1}$) thanks to its good spatial and energy resolution\nas well as the low radioactivity materials used in the construction of the\ndetector. For the second phase of the experiment (2005-2007), the detector will\nbe upgraded by adding a shielding and including focusing optics. These\nimprovements should allow for a background rejection better than two orders of\nmagnitude.",
