Abstract
The Submillimeter Array (SMA) is a new interferometer dedicated to observations in millimeter and sub-millimeter wavelengths. It is located on Mauna Kea, Hawaii, near the CSO and JCMT facilities and was commissioned in November 2003 [2]. The array consists of eight 6-meter diameter antennas which can be moved among 24 pads on the sides of four Reuleaux triangles, producing a maximum angular resolution of 0″.1. Each antenna is equipped with a cryostat at its Nasmyth focus which will accept eight receivers covering all usable bands from 175 GHz to 920 GHz. Signal processing is performed on a special purpose XF correlator, which is based on an ASIC developed at the Haystack Observatory and the NASA/SERC for VLSI Design. The highly flexible correlator will accept two channels of 2 GHz bandwidth from each antenna, making possible either dual polarization or simultaneous dual frequency operation. A pilot program to include the 15m JCMT and 10.4m CSO as part of the SMA will begin in 2005.
