The
Submillimeter Array (SMA) is an 8-element radio
interferometer located atop
Maunakea in
Hawaii. Operating at frequencies from 180 GHz to
418 GHz, the 6m dishes may be arranged into configurations
with baselines as long as 509m, producing a synthesized beam of
sub-arcsecond width. Each element can observe with two
receivers simultaneously, with 12 GHz bandwidth each per
sideband, for a total of 48 GHz processed bandwidth. The
digital correlator backend provides a uniform resolution of 140
kHz, across the entired processed bandwdith. The Submillimeter
Array is a joint venture of the
Smithsonian Astrophysical Observatory
and the
Academia Sinica Institute of Astronomy and Astrophysics.
