[First North American ALMA 12-meter antenna]

On 6 February 2009 ALMA Director Thijs de Graauw, and the NA ALMA Project Director, Adrian Russell, signed the conditional acceptance agreement for the first Vertex Antenna. The 12-meter-diameter antenna is the first of twenty-five being provided by North America’s ALMA partners, whose efforts are led by the National Radio Astronomy Observatory (NRAO) and supported by the U.S. National Science Foundation (NSF) in cooperation with the National Research Council of Canada and the National Science Council of Taiwan. The antenna was manufactured by General Dynamics SATCOM Technologies. ALMA ESO/NAOJ/NRAO image.
