ALMA Memo 354 Choices of Antenna Size and Number for the Atacama Compact Array

The lack of large scale structure in array maps is the result of the hole in the center of the visibility plane that arises because the smallest spacing between antennas is limited to one antenna diameter. Visibility data may be extracted for a region in the center of the hole from a single antenna map made with one array antennas. This can be accomplished by Fourier transforming the map and di...

The Atacama Large Millimeter Array (ALMA)

The Atacama Large Millimeter Array, or ALMA, is an international telescope project which will be built over the coming decade in Northern Chile. With over 7000 m of collecting area comprised of 64 12m antennas arrayed over baselines up to 14 km in extent, ALMA will provide images of unprecedented clarity and detail. One revolutionary feature of ALMA will be its ability to combine interferometri...
