The ALMA Front Ends; an Overview

摘要

The Atacama Large Millimeter / submillimeter Array will be an astronomical facility operating in the millimetre and sub-millimetre range (31 GHz - 9S0 GHz) currently under construction on a plateau in the Chilean Andes. The array will consist of at least 66 Cassegrain type reflector antennas, total collecting area nearly 6000 m~2, operating as a synthesis aperture interferometer. This article provides an overview of the receiver system design, including key performance parameters, project organization, and current project status.
