The Millimeter Array

Authors:
John E. Carlstrom
Abstract:
The U.S. National Radio Astronomy Observatory (NRAO) has proposed to build a large interferometric array, the Millimeter Array (MMA), for astronomical imaging at wavelengths ranging from 1 cm to 350 µm. The design of the Millimeter Array calls for 40 telescopes 8 m in diameter for a total collecting area of 2000 m² . The array is to be located on a high dry site; a 5000 m plateau in Chile and a site at ~3500 m on Mauna Kea, Hawaii are being tested. This paper provides a brief overview of the project including the astronomical motivation and resulting design specifications. The technological innovations required to meet these specifications will challenge researchers of all fields of engineering and device physics. Of particular interest for the participants of this symposium are the specifications for fast electronically tuned local oscillator sources spanning the entire frequency range and also for extremely low noise, image separation SIS mixers.
