Completion of Atacama Compact Array
23 May 2013
The last 7-metre antenna forming the Atacama Compact Array (ACA) has been delivered to the ALMA high site. The ACA is a subset of 16 closely separated antennas, four 12-metre and twelve 7-metre antennas, produced in and delivered by Japan. The ACA is crucial for filling in the short spacings in the uv-plane coverage of ALMA and for total power measurements. The ACA has been named the Morita Array after Professor Koh-ichiro Morita, who died in 2012 and was closely associated with the development of ALMA. Read more.
