The ALMA Project
Atacama Large Millimeter/submillimeter Array
one of the largest ground-based astronomy projects of the next decade
Atacama desert, Chajnantor plateau - altitude 5000 metres
66 high-tech antennas  working as an interferometer
Observing in 0.3 to 9.6 mm range  sub-millimetre
12-m array: 50 antennas
Compact array: 4 12-m and 12 7-m antennas
Antennas can be moved: 150m to 18km
 ‘zoom’

The ALMA Project
An international endeavour: East Asia
(Japan & Taiwan), Europe (ESO),
North America (USA & Canada),
and Chile
Timeline:
• Construction started in Nov. 2003
• First antennas in 2007

A Technological Challenge
Operating at 5000 m altitude
Highest scientific building
Air is thin - only 50% of sea level oxygen
Desert Area - extreme conditions
115-ton antennas will be moved regularly
Superconducting receivers operate at -269 degrees Celsius
