Atacama Large Millimeter Array
(ALMA)
(large radio telescope array in Chile)
The Atacama Large Millimeter Array (ALMA)
is an interferometer array of radio telescopes on
the Chajnantor Plateau
in the Atacama Desert in Chile.
Construction began in November 2003 and
inauguration was on March 13, 2013.
It sits at an altitude of 5000 meters
and consists of
66 12-meter and 7-meter movable dishes that
observe millimeter and sub-millimeter wavelengths.
Operation began with 50 12-meter dishes.
A later additional called the Atacama Compact Array (ACA)
consists of sixteen additional 12-meter and 7-meter dishes
with different characteristics, including a wider field of view.
