ALMA - Atacama Large Millimeter Array

Program Description: ALMA is the largest astronomical project in existence, a single telescope composed initially of 66 high precision antennas located on the Chajnantor plateau, 5000 meters altitude in northern Chile. When completed early in the next decade, the Atacama Large Millimeter/submillimeter Array (ALMA) will be among the most powerful telescopes ever built. Currently under construction in the thin, dry air of northern Chile's Atacama desert at an altitude of 5,000 meters above sea level, With unprecedented sensitivity, resolution, and imaging capability, it will explore the universe via millimeter- and submillimeter-wavelength light, one of astronomy's last frontiers. ALMA will open a new window on celestial origins, capturing new information about the very first stars and galaxies in the universe, and directly imaging the formation of planets. This one survey will drive all sorts of science programs; programs such as weak lensing, supernovae and transient astrophysics, milky way structure, solar system inventory, and individual science collaborations. Full operation started in 2013 and is projected to work through 2023.

Year Started: 2013.

Organization Description: An international partnership among East Asia, Europe, and North America with the Republic of Chile is building ALMA and is funded by the NSF’s National Radio Astronomy Observatory, National Astronomical Observatory of Japan and the European Organisation for Astronomical Research in the Southern Hemisphere. Collaborations include scientists in computer and information science and engineering, With the exception of Chile and an Institute in France, the institutional members are all in the United States.

Data Description: The ALMA Correlator output is specified at 6-60Mbytes/sec. Maximum estimated data through 2020 is about 600MB annually; expected to jump to 2GB in 2021. Once in operation, the data stream to be collected is about 18 Terabytes per night (1/2 gigabyte per second). Researchers require daily large file transfer and grid computing (machine to machine) at speeds between 100 Mpbs to 1 Gbps.
