NRC-HIA: Atacama Large Millimetre Array (1503 words)
	The Atacama Large Millimetre Array (ALMA) will be one of astronomy's most powerful telescopes, providing unprecedented imaging capabilities and sensitivity many orders of magnitude greater than anything of its kind today.
	The millimetre instrumentation laboratory of NRC Herzberg Institute of Astrophysics in Victoria, BC, is one of the few facilities in the world with expertise in superconducting detector technology for millimetre waves.
	Since atmospheric water vapour absorbs millimetre waves, ALMA will need to be constructed in a very dry area, preferable at a very high altitude.
