Scientific paper

The design of the ALMA antennas began in 1999 with a prototyping phase. Two antenna prototypes were built, extensively tested at the VLA site in New Mexico and evaluated in 2003. It was decided to proceed to procurement with two parallel calls for tenders based on the two prototypes. In 2005 contracts were placed with the US VertexRSI and the European AEM Consortium for 25 antennas each. An update on the two designs and the production progress is presented. The Japanese antennas (both 7 and 12 m) are being built by Mitsubishi, which also built an additional antenna prototype. The first antennas have recently arrived at the integration facility at the ALMA Operations Support Facility (OSF).
