AMiBA is an interferometric experiment designed to study cosmology through the observation of the anisotropy in Cosmic Microwave Background (CMB). In 2007 it focuses on the observation of galaxy clusters via the Sunyaev-Zel’dovich (S-Z) effect. Currently AMiBA operates at 86-104 GHz with 7 close-packed antennas of 60 cm in diameter giving a synthesized resolution of 6 arcminutes. In this talk, we will report the results of the first-year observation in 2007 on several massive low-redshift (0.08 < z < 0.33) clusters, including their images and preliminary science results. Data analysis and possible systematic effects will be also addressed. We will also discuss the prospects of the expanded AMiBA that will start operating in 2009.
