Abstract
The Atacama Large Millimeter Array (ALMA) is a millimeter and submillimeter astronomical observatory being built in northern Chile. The array consists of a 12-m array (50 12-m antennas) and of the Atacama compact array (4 12-m antennas and 12 7-m antennas). The ALMA antennas are required to meet very stringent technical specification such as pointing/tracking accuracy, fast motion capability, and surface accuracy etc. under operating conditions. The paper describes the design features and summarizes major performance of the ALMA antennas.
