The Atacama Compact Array, ACA, is a subset of 16 closely separated antennas that will greatly improve ALMA's ability to study celestial objects with a large angular size, such as molecular clouds and nearby galaxies.
The antennas forming the Atacama Compact Array, four 12-meter antennas and twelve 7-meter antennas, were produced and delivered by Japan.
In 2013, the Atacama Compact Array was named the Morita Array after Professor Koh-ichiro Morita, a member of the Japanese ALMA team and designer of the ACA, who died on 7 May 2012 in Santiago.
