Allen Telescopes Array

See also: ATA

The Allen Telescope Array (ATA), known in the past under the name of One Hectare Telescopes (1HT), is a Radiotélescope interferometer installed on the site of the radio operator Observatoire of Hat Creek to the Lassen Volcanic National Park in the Comté of Shasta in the north of the California (the United States).

Joint project of the institute SETI and the Radio operator Astronomy Laboratory of the university of Berkeley, it is intended for the Astronome S and the project SETI. Its name was allotted in the honor of Paul Allen, cofounder of Microsoft and the main thing Mécène of this project.

The observatory is currently composed of 42 antenna S (ATA-42) 6,1 meters in diameter and should represent from here June 2008 a park of 350 antennas (ATA-350) functioning in network and distributed on a surface of 1 km diameter. It would have, at this time there, to have a sensitivity of observation equivalent to a Télescope 100 meters in diameter and it will be then largest and fastest in the world. It will make it possible, amongst other things, to supervise a million star S in the search of radio operator signals of origin Extraterrestre, of power equivalent to the emissions generated by the Radiotélescope of Arecibo. The Band-width useful will be of less than 1 Ghz to more than 10 or 25 Ghz. Its overall costs are estimated at 25 million dollars.
